The Primordial GuardianTimothy WongRSN: Timothy XD

CAim of Boss:

To create a boss that is heavily based on Teamwork, and is tremendously difficult to defeat with the rec-ommended number of teammates, with each person carrying out their roles.

To make players required to use and know their abilities well; and apply them at the right time.

To make ore use of normally overlooked factor of the game - for example the weight of a character andtheir equipment.

To encourage communication and planning across a team base; so that working together will make theboss fight go much smoother.

To remove time-based deaths; for example - [if you do not click this ability within this timeframe; you willdie] - the boss should offer different decisions for the player; where they can decide the best way to es-cape a certain attack depending on the situation of the team, and failure to do so does not conclude ininstant death or taking a large hit; but rather being transported to another part of the fight to fight them-selves back up. This will also further encourage team communication.

To have a boss fight not just be a boss fight - to tell a story through the boss fight rather than another mon-ster to camp for drops.

Fitting in with RuneScape LoreDuring the creation of the Elder Artefacts, multiple were created before the finalisations of the ones weknow of today. However - a second set of all 12 Artefacts were put into storage and safekeeping by theElder Gods. This secondary set, though weaker than their primary versions, are still a force to be reckonedwith.

Created by the Elder Gods as a guardian of the Elder Artefacts, Custos (Latin for Guardian) was formedsoon after the creation of the Elder Twelve. With all 12 Artefacts present at the hands of the Elder Gods atthe time; the perfect Guardian to protect them was thus created; tuned finely and imbued with all the im-mense power from the Originals.

To ensure the security and to prevent false users from accessing such powerful objects, Custos cannot bedefeated even by the power of a single Elder Artefact, never mind mortal weaponry. To effectively defeatCustos, the power of all 12 Artefacts remaining within his keep must be channelled through a medium im-mune to God Magic - The World Guardian.

Custos was created and programmed to do just one thing: To protect the Artefacts from falling into hewrong hands, and he will do whatever it takes to protect them.

LocationAccessed by going through The World Gate - The World Guardian must bring The Measure; in order to trackdown the Primordial Realm - the land of sacred clay, and the land where all was created by the Elder Gods- the land with the highest ever seen Anima levels.

The primordial Realm has lands made of sacred clay, a perfect -but dangerous- environment for Custos.Custos will take advantage of the Elder energy he possesses along with the versatility of sacred clay to ma-nipulate and transform the environment to suit his needs in defending the Artefacts.

Phase BreakdownThe intention of this boss is to surprise players with whats coming next. Therefore, what phase and whatmechanics Custos chooses is heavily dependant on what the group does.

Phase BreakdownEnvironment will change from phase to phase. The phase in which Custos will enter next is determined byseveral factors which can only be controlled by the team. However, the landscape of entrance every timewill be the same - bears striking resemblance to stealing creation - where the floor is sacred clay, and willbe formed into the required environment depending on what mechanic of the boss is triggered.

Phases below will not be numbered, but rather go by name, as they do not appear in chronological order,but rather dependant on the fight: The name will reflect the condition for it to enter the respective phase:

Entrance PhaseTheSource

The entire area, created by sacred clay; and pulsat-ing with energy. However, ages of abandonmentleaves it in a ruin-like state. However, Elder Energyremains to protect the area, shown by the glowingdoor supports and struts. The area was built to beGod-proof, and the only way this was achievable wasthrough God Magic itself. However, with the dawn ofthe sixth age, The World Guardian, immune to GodMagic, can enter.

Upon entering this phase, one player must touchThe Ornament in the middle to alert Custos. Modelled on Autodesk Maya | Student Licensed

Area One

The Ornament

The Glistening Gate

Modelled on Autodesk Maya | Student Licensed

Once a player comes into contact with The Ornament,Custos will form out from the floor out of Sacred Clay,and begin attacking. In this area, if players may notstand on the sides (marked sacred spike area on theArea One map), or Custos will form sacred spikes to pro-trude from the walls and bleed the player for 500 dam-age per 0.5 seconds, incrementing by 150 damage perbleed up to a maximum of 1100 damage.

Sacred Spikes

During this phase, as a part of Custos ability rota-tion, he may also form a sacred shield out from thefloor as shown below, in front of up to half the team:

If a shield is summoned in front of an attacker, theplayer will be bound to the spot; this can be clearedby using Freedom. Any additional damage will alsobe blocked and absorbed by the shield. The shieldwill absorb all incoming damage, and after 5 sec-onds, will reflect 50% of this damage back onto theplayer as magic damage, whether or not they havemoved away from the shield. If the player remainsbehind the shield when this happens, it will closeonto them and deal an additional 2000 typelessdamage. This Shield however, will also block anynon-melee damage coming from the boss to you.

The Shield

Note: unless stated otherwise, typed damage (me-lee, ranged, magic) may be stopped using reso-nance, devotion (with correct prayer), barricade.Typeless damage can only be barricaded.

Attack Rotation and Mechanics for The Source1. Players enter the Glistening Gate, prepare and get ready to fight.

2. One player (Most likely the Tank) touches The Ornament, and Custos spawns.

3. As Custos spawns, the first attack he will do is slam the Ornament, unleashing an Area of Effect Mag-ic attack covering the entire room, hitting all players for ~4000.

4. Custos will begin attacking a single player after this, either at random with Ranged and Mage fromafar, or melee if the player is up close. Or if he is Provoked, he will remain to attack one player.

5. After 5 auto-attacks, he will raise his arms and call Sacred shields to block and reflect damage to upto half of the team members, this is repeated 3 times in succession, whilst at the same time still attack-ing one person (Tank).

6. Once the last shields have been summoned, Custos will attach himself to the walls and begin to buildElder Energy. During this time, a barricade will appear around Custos, rendering him immune to dam-age. Players will also be energised due to the entrance of Elder Energy into the area, and will deal 300%damage. For every 1000 damage inflicted on Custos during this barricade attack, he will deal 10%more damage for the rest of the fight. However, for every 500 lifepoints healed using Defensive abilitieswill lower Custos upcoming damage by 5%. (Players should aim to use regenerate or rejuvenate to low-er damage). This also applied to the Ornaments AOE attack.

7. Custos comes out from his barricade, does 5 auto-attacks. He will then shatter the two walls on ei-ther side of him, sending fragments of sharp sacred clay at all players, giving each a 1500 bleed per 1second. This can be cleared by Freedom. Custos will also heal to half lifepoints.

8. The walls adjacent to Custos will slowly rebuild during the fight. The groups job at this point is to domaximum damage per second to get Custos down before he heals again.

9. Custos will rotate from Step 3 until 0 lifepoints.

At 0 Lifepoints:

A Cutscene will play of Custos releasing hold on The Ornament, and a player is selected at random totouch the Ornament and imbue themselves with its power. A counter will appear on the screen saying2/12 Artefacts activated (The Measure the group already holds is included)

The floor marked on the map will then collapse. If Custos is moving to Area 7 (Condition 6), he willsmash open the wall behind him and move onto the next phase (Condition 6).

Additional:

- Any bleeds inflicted on Custos during this phase will heal him (only entrance phase).

Map

Phase Breakdown- ConditionalsThere are 6 conditional phases that Custos may choose depending on what conditions were met on phaseone. To prevent the same rotations appearing again and again, the mechanism works as below:

- When a condition is met, the game engine ticks the appropriate area, and adds it to a list of potentialupcoming phases.

-If only 3 conditions are met, then the game engine will randomise these and make Custos change phase,the order unknown to the players.

-However, if more than 3 conditions are met, the game engine will select two based on the order of the con-ditions met - so first two may be determined by players, and the remaining conditions that were met wouldbe randomised.

In each conditional room, an Elder Artefact exists, and Custos will use its power in order to try and defeatthe players. At the end of each phase, one single player of each group must also go up and touch the arte-fact, in order to imbue the team with power.

Below is a breakdown of the boss mechanics of each conditional area:

Conditional 1 - Wall Collapse Escape

This phase initiates if, on phase One, Custos was able to heal to half health between 1-3 times, inclusive.The basis of this level is straightforward. Once players drop down from the top level, the east wall will im-mediately begin collapsing. A shadow will form where the rocks will land, and players must move fromthese locations to avoid being hit an initial 3000, with additional bleed damage of 300 per 0.5 seconds +Stun. This stun can be cleared by Freedom.

When the Elder Artefact is within view, Custos will go over to it and use it against the team. Effects werecovered before.

Toward the end of the phase, Custos will use a bomb attack, in which one of the two outlined safe-surgezones on the maps will be active, and players must stand on it to prevent being blasted.

Area Two

Conditional 1 - Attack rotation and Mechanics1. Players drops down from phase One, Custos follows quickly after.

2. Custos raises hand and begins to collapse the east wall, and the entire tunnel.

3. Custos does 4 auto-attacks before the next segment of the wall collapses. Players should move whenshadow appears.

4. After the third collapse, Custos will once again begin summoning reflecting shields, mechanics wereexplained earlier. This will persist throughout the rest of the phase.

5. Custos will remain to heal up until the sixth wall collapse. At this point, once players weaken Custos to25% Health, Custos will heal up to 75%, before harnessing the power of the Elder Artefact.

6. Custos shield ability will stop after the ninth and final wall collapse.

7. Custos will then stand near the exit to the tunnel, and begin to unleash powerful attacks hitting be-tween 6000-8000. Players may avoid these by standing on the safe zones that will be marked on theminimap ONLY.

8. Once Custos reaches 0 health, he will drop the Artefact which he picked up, and a player must touch itand imbue he power onto the team.

9. Custos will then retreat into the cave exit; and players should follow to advance to the next stage.

Conditional 2, 3, 4, 5, 6

The remaining conditionals have a similar rotation to Conditional One. The Differences lie in the room lay-out, as well as the Artefact spawn found on that specific rotation.

Below breaks down the specials of each conditional possible. Buffs which Artefacts can grant Custos werecovered in the section earlier.

Conditional 2 - Unstable PillarsOn this conditional, Custos can only attack using ranged and magic. His attacks will always hit everyone inthe team. One player must hop across the pillars in order to reach the Elder Artefact. However, some pil-lars are unstable and will collapse. This will cause the player to jump to the nearest pillar and be dealt6000 damage. This can be avoided by looking closely at the pillar before jumping.

No special attacks are gained by Custos on this phase. However, he will focus much stronger attacks onthe jumper. Therefore, it is recommended that this player has high lifepoint boost, as will as a good knowl-edge of defensive abilities.

Conditional 3 - The Moving Earth

This conditional consists of 3 main floating platforms. These platforms and continuously shake, thereforethe gap between them will oscillate between big a small. Upon falling down to this stage, players mustsurge at the correct moment to get over the rocks. If they surge at the wrong time, they will fall throughand die. On the second platform, Custos will summon clay basilisks to attack the players. These are level650, and are highly dangerous. They can use AOE attacks, so it is recommended for players to spread out.

Once the basilisks are dead, 3 Seismic Wizards will be located at the edge of the Third platform. They areusing Elder Magic to Push Custos to safety. These must be defeated in order to have the platform whichCustos is on float back, so that players can surge over.

Seismic Wizards are mortals, imbued by Custos with Elder Magic and have a combat level of 1560. Theyhave combo attacks similar to the Barrows Brothers: Rise of the of Six, in which they can aid each other inthe fight, as well as being able to re spawn if not killed within a certain time.

Upon reaching Custos, he will attack with his normal auto-attacks, AOE attacks and normal specials rota-tion. However, when below half health, Custos will gain an earthquake AOE, which cracks the earth anddeals 1000-2000 damage constantly. However, this damage can be lowered by inspecting the ground forless cracked places, and moving to them.

Conditional 4 - Mirror Image

This conditional sees Custos splitting himself into two parts, one located either side of a PolyPortal. Theraid team must now split according to what style Custos is using. This is random and for fastest boss killtime, players should use their combat triangle knowledge to split the team. Once split, Custos will continu-ally attack with auto-attacks either side of the portal, as will as normal AOEs and special attacks.

Players on either side must attack Custos, and fix the bridge so that they can walk over to him. The aim ofthe phase now is similar to Vorago, except it is timed.

Both teams on either side now must deal as much damage as possible to push their version of Custos in-to the polyportal. Both versions must enter the portal within 3 seconds of each other, or else they will re-set.

Conditional 5 - Rage

Upon entrance to this conditional, players will find themselves in a large circle room, with Custos in thecentre. Upon entrance, players must click the Divine Barricade Energy Channel directly in front of them.This will drain players adrenaline to form a barricade, as Custos will release a very powerful attack whichwill hit everyone for 90-100% of their lifepoints. The more adrenaline the Energy Channel absorbs, theless damage the team takes.

On the North and South sides of the room are located Eagle Platforms. Attacking Custos from one of thesewill yield a 15% Damage boost to both Magic and Ranged. An Energy Channel can also be found on these,as Custos will continue to use his powerful charging attack. Players should decide whether to split up ornot.

Conditional 6 - Reflects

On this phase, Custos cannot be attacked, and his health will also reduce down to 100,000. Players willbe on a separate room from Custos, only visible through a small gap in the wall.

The point of this phase is to kill Custos using defensive abilities and reflects only. Custos will do attackson random players, as will as AOE attacks. Spells such as Vengeance and deflect prayers will also do dam-age to Custos.

It is recommended that players are competent at using defensive abilities, as will as have healers andsupport roles among the team. Damage should also be negated where abilities are not able to be used, orare on cool down. Resonance will also help very much on this phase.

Once Custos is defeated, he will retreat to the next phase, and the players will not be able to cross thebridge and imbue the Artefact.

The Median - BreakdownOnce 3 Conditional phases have been defeated, Custos will then initiate The Median phase. In thisphase, Custos will once again remain in the middle, using his usual attacks. However, for his special onthis phase, Custos can channel energy pulses from the walls to fire into the ring in which players cannotmove from.

During this phase, the energy beams can be reflected using the Reflect ability. It also gains an extra 25%effectiveness, so will reflect 75% of the damage onto Custos, whilst blocking 50% of it to the player. Thisdamage cannot be resonanced, but can be barricaded against.

Upon completion of the phase, the players gain the power of The Locator. This allows the players tochoose which Artefact they want to encounter on the first Island of The Isles, which is the next area.

The Artefacts they can choose from will be the ones that have not been encountered in the conditionals.

The Isles - BreakdownThe Isles is an open area, suspended in Primordial Space, surrounded by Energy. Upon the entrance toThe Isles, Custos will land on the Island which the players selected using The Locator.

On The Isles, Custos himself has a 100% damage boost throughout the entire phase, and does notchange on what island is jumps to. The order in which he initiates the Artefacts is random, apart from thefirst, which is chosen by the team.

Between each island phase, Custos will pull the entire team to the central rock. This is where taking noteof the weight of each character is important. Custos will slam the rock pillar, so that is become unstable.Players must move accordingly to the rock, to balance it out. If the rock falls, it takes all players with it,and the fight is lost.

After every balance, players must also surge off the rock in order to get off.

At the end of each Island phase, one payer of the team must also touch the Artefact to imbue its power.

At the End of The Isles, all Island will collapse, and take the players to the final area. The final area is cho-sen based on how much of each style of damage what inflicted onto Custos throughout the ENTIRE fight -from the very start. If Melee was the most used style, Custos will use Mage in the final stage and so on,from the combat triangle.

The Closing - BreakdownKnowing that he is losing the fight, Custos will draw all the power that he has remaining, unleashingstrong AOE attacks onto the team, with the style of the attack dependant, as explained before. Thisphase is the easiest of all phases, as no specials will be used.

At 1000-5000 lifepoints remaining, the team must gather in a line in front of Custos to Channel all thepower into him to defeat him.
