Kor'kron Dark Shaman

Earthbreaker Haromm and Wavebinder Kardris have a shared health pool.

Haromm strikes the tank for heavy Frost damage and applies a stacking debuff that increases damage taken from Froststorm Strike by 25% for 30 seconds.

Requires a tank swap.

A 1.5-second cast directed at the tank, Froststorm Bolt does massive Frost damage roughly every 10 seconds.

Darkfang and Bloodclaw are the Dark Shaman's mounts.

They both share the same two abilities, Swipe and Rend.

Swipe is a frontal cleave that deals Physical damage and must be pointed away from the raid.

Rend is a stacking bleed that deals moderate damage as it ramps up.

There is no need to rush to kill these. Using dots and passive cleave is sufficient.

Upon reaching 25%, the bosses will pop Bloodlust, gaining 25% haste and increasing damage done by 25%.

Toxic Mist lands on random players and deals moderate Nature damage every 3 seconds for 30.

Every time this ticks, the player gains a stack of Toxicity, taking 10% increased Nature damage.
