Abuse the Ooze
Defeat Sjonnir the Ironshaper in the Halls of Stone on Heroic Difficulty and kill 5 Iron Sludges during the encounter.
Abuse the Ooze requires you to defeat Sjonnir the Ironshaper in Halls of Stone on Heroic difficulty while killing 5 Iron Sludges during the encounter.
Enter Halls of Stone
Enter Halls of Stone on Heroic difficulty and begin the fight with Sjonnir the Ironshaper. If you are at max level, unequip all of your gear before engaging him to avoid dealing too much damage.
Burn Sjonnir to 50%
Use your lowest-damage abilities to bring Sjonnir down to 50% health, at which point he begins spawning Malformed Oozes. Stop dealing damage to the boss once he reaches around 40-50% health.
Let Oozes Merge
Allow the Malformed Oozes to move toward each other and merge — two oozes will meet in the middle, dance around each other for roughly 5 seconds, and then combine into a single Iron Sludge.
Kill 5 Iron Sludges
Kill each Iron Sludge as it forms; wait until at least 5 have merged and been killed before finishing off Sjonnir. If you are at max level, a single punch or low-damage ability is enough to kill each Iron Sludge.
Kill Sjonnir
Once 5 or more Iron Sludges have been killed, finish off Sjonnir the Ironshaper to complete the encounter and earn the achievement.
Tips
If the Iron Sludges are dealing too much damage, apply damage-reduction debuffs such as Curse of Weakness, Thunder Clap, or Demoralizing Shout to Sjonnir to reduce the pressure on your group.
