Boss fight mechanics/ideas

LilWeembo

Had some free time so I thought id write out some mechanics for a boss fight I thought might be interesting. Gives the players a bit of option when engaging the fight so they can choose based on the groups composition/gear/skill.

Boss fight (Fire Demon)

Scene
¬Set in a volcano
-Walking through a tight corridor you emerge into a large cavern standing at the top of a staircase
-Steps lead down to small surface which splits into 2 bridges that angle away from each other and service their own large circular platform which are suspended in air by chains attached to the ceiling of the cavern.
-Below the suspended platforms is a pit of bubbling lava blanketing the entire cavern floor
-In the center of each platform is a caged weapon (sword on the left, shield on the right) which is suspended over a hole in the center of the large platform
-Each cage is magically secured by runes which are carved into 3 statues per platform
-A 3rd larger cage hovers in between the 2 large platforms, any chance of seeing inside the cage is blocked by the solid ice that engulfs it

Overview
Phase 1:
The raid choses which platform to attack sword or shield, doing so determines the later mechanics of the fight. To release one of the caged items players must destroy each rune on that platform which is carved into a statue. As soon as any amount of player damage is done to a statue the fight begins, phase 1 begins and that statue comes alive. If at any point damage is done to any other statue on that platform that statue will come alive. When the fight begins and a statue becomes alive the opposite platform becomes engulfed in flames breathed magically by the 3 statues on that platform. When all 3 statues on engaged side are destroyed the item centering it is released from the cage and falls through the hole in the platform which is then destroyed by the lava below.
Phase 2:
This release loosens the 3rd magically frozen cage in the center which houses a Fire Demon (just the first monster that came to mind) and he emerges from that cage in a rage, infuriated by the fact his (item) has been destroyed by the lava and leaps to the unaffected platform and retrieves the other weapon. At this time the raid is forced to vacate the platform they were on as it begins to crumble and phase 2 begins as they must go to the other platform.

Mechanics
Phase 1:
-Statue must be tanked

-Smaller minions spawn from the statue which fixate targets

-Statues “roar” causing few clusters of small rocks and 1 larger rock fall from the ceiling onto the platform. -The larger rock needs to be soaked. It does 50% of a player’s maximum health split up to 2 targets. If no one soaks the Large rock it crashes through the platform creating a hole which players can fall through.

-The longer the fight goes on the more the magical prison holding this cavern together loosens and the increased heat causes additional effects which include:
-Spits of lava – below the lava bubbles and a spit of lava shoots out and hits a target (non tank) burning them doing heavy damage over a short amount of time. Needs to be heavily healed or mitigated. Cannot be dispelled
-Small rocks fall from the ceiling hit random areas on the platform which need to be avoided, happens more frequently the longer the fight goes on.

Phase 2:
-Statues reduce the damage the boss takes by 30% each for a total of 90%. Killing a statue removes this buff so killing all statues is ideal for the players.

-All mechanics from phase 1 remain

Boss mechanics

If boss wields the sword: sword oozes lava
(idea is to make this more of a heavy single target healing fight)

-Boss does +10%dmg

-Cleave attack in a frontal cone, occasionally does a higher damaging hit

-Lunge – Boss turns and lunges at a target piercing them and anyone in the way. Applies spit of lava to targets hit and buffing himself with fiery rage for each player hit.

-Fiery Rage – the boss becomes enraged as he continues to fight the same target buffing himself with a +2% dmg increase every 5 seconds. Stacks are removed when he no longer has that target as his primary target, stacks take 20seconds to fall off – stacks are based on each target so with 2 tanks taunting off each other he should have 2 different fiery rage buffs. Ideally the stack timing to fall off would be around the same time it takes the players to kill a statue. So when a statue dies the tanks would swap roles.

-Tidal Lava – boss conjures the lava below to come crashing over the platform in a wide line that stretches the diameter. This applies “Spit of lava” to players hit

If boss wields the shield: shield has cracks in it which emit flares of fire

(idea is to make this more of an aoe healing fight)

-Boss has +10% dmg reduction

-Boss Slams shield on the ground every few attacks doing damage to all players in a 10-yard radius

-Demonic Grip – Boss snatches up the second on threat target within 10 yards crushing them(they take dmg) rendering them immobile and silenced while continuing to attack his main target. The snatched played is released only when the boss takes a certain amount of hits. The snatched player may be healed. If only the tank is in range when Demonic grip goes off, he snatches the tank and will continue to attack the next target on his aggro list.

-Leap – Boss Leaps to a target doing damage and stunning them from 5 seconds and causing “Roar”– if anyone else is in the area he snatches them up (Max 1 target) with his free hand causing “Demonic grip”

-Shattering blow – the boss’ attacks are so powerful they crack the armor of the target increasing the damage they take by +1%. Stacks are removed after 20 seconds. Every 5 stacks the boss senses the targets weakness and begins to attack faster trying to end the foe. It’s a stacking Attack speed buff lasting 5seconds.

-Tidal Lava – boss conjures the lava below to come crashing over the platform in a wide line that stretches the diameter. This applies “Spit of lava” to players hit
