Momma Said Knock You Out (10 player)

Momma Said Knock You Out (10 player) is a dungeon & raids achievement earned for defeating Grand Widow Faerlina in Naxxramas on 10-player mode without dispelling frenzy.

You'll need to either kite her between two taunting tanks using cooldowns, or burn her hard while the healers attempt to keep the tank alive through ~20k melee hits. For a Naxx-10 geared tank, this encounter is fairly easy; She will only melee you for around ~15k at the worst. Save all your defensive cooldowns for the frenzy. DPS should save all cooldowns for the frenzy as well. Bloodlust/Heroism is especially useful here.
