Darius' basic attacks and damaging abilities cause enemies to bleed for 12 / 15 / 18 / 21 / 24 / 27 / 30 / 33 / 36(+ 30% bonus AD) magic damage over 5 seconds. This stacks up to 5 times for a maximum of 60 / 75 / 90 / 105 / 120 / 135 / 150 / 165 / 180(+ 150% bonus AD) magic damage over the duration.
Darius gains 5% movement speed for each bleeding enemy champion.
Noxian Guillotine does not go on cooldown or consume mana until the he strikes the target (being blocked by a spell shield or invulnerability still counts as striking the target). If Darius' target dies before the axe hits or if he is interrupted, he can instantly reuse the ability.
The cooldown of Noxian Guillotine will begin the instant Darius first casts the ability, not when the buff expires, and will continue to tick down even as Darius reuses the ability multiple times. Five consecutive executions with maximum delay between casts will remove 100 seconds of downtime from Noxian Guillotine, which leaves only 20 seconds of downtime at rank 1 and no downtime at ranks 2 and 3.
During the leap, Darius is considered to be channeling and can be interrupted by hard-CC. It is worth noting that entangle and root are not considered forms form of hard-CC.
Noxian Guillotine will apply one stack of Hemorrhage, although it will not be considered for the damage dealt.
