With Open Arms (25 player)

Enter Ulduar and engage Kologarn. The key constraint is that neither arm can be destroyed during the fight, so avoid sustained arm damage beyond what is needed to free players from Stone Grip.

When Kologarn grips players with Stone Grip, dealing roughly 20% of the right arm's health (approximately 404, 870 damage) will cause it to release the gripped targets. Limit arm damage to only what is necessary for each grip release and avoid killing either arm entirely.

After freeing players from the first few grips, allow healers to keep gripped players alive as long as possible rather than breaking the arm — though be aware that letting players die to the grip appears to reduce the frequency of grip casts. Use Battle Resurrections and other combat revival abilities to recover lost players.

Use Heroism or Bloodlust at around 95% of Kologarn's health to maximize the number of players alive who benefit from the buff, then push maximum damage on Kologarn himself — not his arms — to end the fight before attrition becomes unmanageable.
