Ugly Tooth
Ugly Tooth slows down enemies when you hit them. The slow stacks up to 3 times for a total of a 30% slow.
The slowdown works on Elites and Bosses, and can make a large difference for those fights.
Ugly Tooth can also be rather powerful with Elemental builds that relies on Burning Damage to kill enemies.
Structures such as Turret or Landmines also applies the slow when they hit a target.
