The Beast

The Furnace
After Rend, climb out of the Stadium into the Furnace and clear the approach to The Beast's room. Clear nearby enemies before pulling, since Terrifying Roar can send players running and Flamebreak can displace the tank. Preserve the cleared room for a possible Lord Valthalak return.

The Beast
Boss BeastThe Beast disrupts a stable tank position with Flamebreak, a charge and Terrifying Roar, so the cleared room must remain safe when players are displaced or feared.
Abilities

Flamebreak
Inflicts Fire damage to nearby enemies, knocking them back.
Brace the tank against a wall to limit Flamebreak's knockback, and keep ranged players away from its nearby Fire damage.

Berserker Charge
Charges at an enemy, knocking it back and inflicting normal damage plus 300.
Berserker Charge can send The Beast away from his tank. Give the tank a clear return path instead of following the boss toward an uncleared passage.

Terrifying Roar
Causes nearby enemies to flee in fear for 5 seconds.
Clear nearby packs before Terrifying Roar can send players fleeing into them, and keep ranged healers back from the nearby fear when possible.
Tank- Use the cleared room's wall against Flamebreak. After Berserker Charge, restore that position without dragging The Beast through the ranged group or into another pack.
Healer- Heal from back in the cleared room to reduce exposure to Terrifying Roar. Be ready to heal a charge victim while the tank recovers from displacement.
Damage- After a charge, let The Beast return to the tank's wall rather than chasing him into a passage. Resume melee attacks only after his position is settled.
