[ELE] Dragon's tooth
This happens when the cast of Dragon’s Tooth is interrupted either by the caster him-/herself (e.g. dodging too early while casting it) or an enemy player (knock down/back, blind, stun, etc.).
The only thing being “bugged” about that is the fact, that the whole animation is still playing after an interrupt and therefore it creates the illusion of the skill not doing dmg without any apparent reason.
Then again, I see no way of the animation being interrupted too, apart from the dragon’s tooth unrealistically disappearing while falling down… shrugs
