Stupor — guide

Gives the Champion a 25% chance to apply a [Sleep] debuff for 1 turn when attacking. Like all control debuffs, the Stun set is useful for Champions with AoE skills. Sleep differs from other control debuffs in that if the hero under the debuff takes damage, they wake up. This means it's better to pair characters in Stun sets with others whose skills do not deal direct damage, such as the [Bomb] skill.
