Trash

• Activating the chain winches will sometimes spawn adds, which the tank should pick up

Bosses

Firemane

• Wisps that reach the fire pit will cause group-wide damage, but it's trivial to heal through
• After killing him, click on the fire to proceed

Thunderclap Guivre

• Will summon lightning elemenatals which need to be burnt
• While the adds are alive the water is electrocuted and will damage you, and the boss is invulnerable

Tangata

• Wisps have the same mechanic as Firemane and can be similarly ignored
• Will summon fire sprite adds and be invulnerable until they're burnt
