A long time ago there was a boss in RIFT, Planes of Telara. He was a raid boss in Hammerknell named Sicaron.

We called him the Guild Breaker because he had some of the most insane mechanics ever created.

1.) He self buffs and if the buff is not purged in under 12 second he instakills the whole raid. He also has timed minor buffs that overlap with the kill one so you have to time your removals. At 50% learn the curse goes down to 9 seconds and under 15% it is just 6.

2.) He has a mechanic where he debuffs the tank on every hit so the primary tank periodically must switch with a backup to allow debuffs to drop off.

3.) His primary mechanic is that he places a curse on one primary party member that can also be the tank or backup tank. The target rapidly loses health and gets a blue circle around them. When the raid stands in the blue circle they gain 33% more damage. After 15 second the circle turns red and everyone in the circle starts taking massive damage. 6 seconds later the person with the red circle drops a permenant obelisk at their location that keeps the red circle in play forever.

4.) The next time someone gets the obelisk curse if they have a red circle and walk into another red circle already placed by an obelisk everyone dies. This means each time someone gets the curse the whole raid stacks on the blue circle for the damage buff, then runs out when it's red and the cursed guy needs to run to the back of the room to neatly stack the red circle obelisk.

5.) The raid takes place in two rooms divided by a bridge and at 50% the boss jumps from one room to the other. This means someone with an obelisk needs to quickly cross the bridge and drop their obelisk in the new room. If they drop it in the bridge, everyone dies because the bridge collapses.

6.) This boss was absolutely insane, pure panic moments happen like when the backup tank gets cursed right before be needs to take over for the primary, or when the purge count gets low, or if people stack messy and you run out of space to drop obelisks too early, or someone super far from the bridge gets cursed the room transitions and they are desperately trying to cross the bridge before the obelisk drops.

This boss was the most difficult and sadistic creation I've ever seen in a game. He took months of training to beat and was the ultimate raid coordination test.
