Miner Johnson

Lumber Room
Beyond Rhahk'Zor's door, check the left-hand mine tunnel for Miner Johnson before entering the lumber room. The side mine is optional. Clear the workroom before engaging Sneed's Shredder so Terrify cannot send a player into an untouched pack. After the machine falls, the tank must pick up Sneed before the group resumes damage.
Miner Johnson
Elite HumanoidMiner Johnson's optional side-tunnel fight becomes dangerous when Pierce Armor overlaps damage from neighboring miners.
Abilities

Pierce Armor
Reduces an enemy's armor by 75% for 20 seconds.
Expect increased physical damage on the affected tank and avoid adding another mine pack during the debuff.
Tank- Clear space in the left-hand side mine before pulling Miner Johnson. Use mitigation during Pierce Armor and keep the fight separate from the remaining miners.
Healer- Watch for Pierce Armor rather than judging incoming damage from the opening swings. Keep healing focused on the tank while their armor is reduced.
Damage- Finish Miner Johnson before advancing into another side-mine pack while Pierce Armor is still on the tank. Return to the lumber-room route when the optional detour is complete.
