Goldie stomps the ground to deal damage on all players, and also spawns several Cinderbrew Barrels and Volatile Barrles.
When these Barrels detonate, they go Cinder-Boom and send fire waves in all 4 directions. The Volatile Barrels will apply a stackable debuff Cindering Wounds aswell, dealing damage over 6 seconds. These Barrels are differently colored, and you should not destroy too many of them at the same time.
When she reaches 100 energy, she uses Let it Hail! which explodes all remaining barrels, causing probably a wipe if too many Volatile Barrels were still remaining, or atleast requiring strong healing cooldowns.
To destroy Barrels in a controlled way, some players are sometimes affected by XX, creating a 5-yard circle around them, and exploding for damage on players and barrels. When a barrel is hit, it explodes with Cinder-Boom and spawns the waves coming out of it.
Cash Cannon is a frontal cone in the direction of the Tank, dealing damage to players struck and destroying any Barrels hit. This does not destroy Barrels that are far away, but only within like 15 yards infront of the boss.
