Ironaya

Map Chamber
Use the assembled Staff of Prehistoria at the model city to open Ironaya's chamber. Gather in cleared space before activating it so her frontal smash and nearby stomp do not catch players still arriving through the passages.

Ironaya
Elite GiantIronaya turns the staff puzzle into a positioning fight around a frontal Arcing Smash and the nearby knockback and stun of War Stomp.
Abilities

Arcing Smash
Lashes out in a vicious arc, inflicting damage to enemies in a cone in front of the caster.
Point Arcing Smash away from the group; melee attack from behind Ironaya rather than sharing the tank's frontal cone.

War Stomp
War Stomp hits nearby players and can knock them back and stun them. Keep the healer out of melee and allow the tank to restore position after it lands.
Tank- Take Ironaya in the cleared chamber with Arcing Smash aimed away from the group. After War Stomp, return her to that facing before melee close in again.
Healer- Heal from outside Ironaya's melee group so War Stomp does not disable the tank and healer together; recover the tank after the stomp while they regain position.
Damage- Attack behind Ironaya to avoid Arcing Smash. Ranged players remain apart from her melee group, and melee wait for the tank to restore her facing after War Stomp.
