Lady Tu de Qing commissioned this gem from the workshops of Xiansai, saying "I prefer my targets asleep or drunk. Barring that, I'll take sluggish."
Notes[]
- Any Crowd Control effect works: the gem's owner, traps or other players.
- An attack that applies a crowd control is not amplified if the target is not under crowd control yet.
- Monsters or Elites with Juggernaut affix are immune to crowd control effects, completely negating the effects of this gem.
Tips[]
- At rank 25, the slow aura makes the gem always work against all nearby enemies.
