Top 3 Best Stunners

1. Krampus Purple Guy: Most consistant stunner on the list, long stuns, and supports the team further by producing 35% more damage to stunned enemies.
2. Frostmancer Withered Bonnie: 1s stun, great if you don't upgrade it to single.
3. Mangle: When an enemy is within its range for a bit, it will stun them for a while. Bad DPS and attack type but the stun is good.
