Similar to Arcway, Waycrest Manor’s route depends on which door is open. And depending on the door, it can significantly frontload the dungeon with trash before you can get to the first boss and get lust/hero on CD. The first three bosses will either be Heartsbane Triad, then Soulbound Goliath, then Raal the Gluttonous, or it will be Raal, then Goliath then Triad.
Using a paladin on this fight will negate the most significant healing issue, Jagged Nettles which requires the healer to heal the target above 90% before it will fall off. Paladins can BoP or Bubble this to remove it. If you do not have a paladin, ask the target to help by using defensives.
Aura of Dread is another major killer on this fight, as players often forget to jump to remove the stacks (similar to the first boss in Court of Stars). Players can very easily kill themselves by not jumping, and currently boss mods are not alerting players they need to jump.
You really only need to worry about the tank if he doesn’t move the boss periodically into fire to remove the stacking debuff.
The other common issue is when players do not run from the Burning Soul adds, or get rooted when no one removes the Soul Thorns, then get hit by the adds.
Raal the Gluttonous
The biggest issue here is when DPS don’t kill the servants when the boss spawns them, as the boss will get a stacking buff that increases damage by 5% for each servant he consumes.
Lord and Lady Waycrest
If you can dispel disease, you can remove the Violent Pathogen as soon as the person moves out, letting them get back to the boss faster.
The healer is the best person to use the vial of Alchemical Fire that spawns on the ground. Use it to burn the corpse of the add when it dies. Because it does a leap, the add might not be under the boss when it dies.
