If Noxian Guillotine kills its target, Darius causes all nearby minions and monsters to flee in terror for 3 seconds and it can be recast within the next 20 seconds at no additional cost. At rank 3, Noxian Guillotine'scooldown resets completely. This can occur multiple times in succession.
Noxian Guillotine will apply one stack of Hemorrhage or 5 stacks of Hemorrhage if "Noxian Might" is active, although the added Hemorrhage stack will not be considered for the damage dealt by Noxian Guillotine.
Noxian Guillotine does not go on cooldown or consume mana until the ability strikes the target (including if it is invulnerable). If the target is killed before the blow hits, it will not go on cooldown.
The cooldown of Noxian Guillotine will begin to tick down after the ability's last cast and not when the buff expires.
Noxian Guillotine has a cast time and cannot be interrupted by anything other than Darius's own death. He will still suffer any crowd control effects, if duration permits, after the cast time ends.
Noxian Guillotine will not do damage to a target that Darius loses sight of. This includes entering the fog of war, a brush, or stealth
