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.
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 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.
Noxian Guillotine will apply one stack of Hemorrhage, although it will not be considered for the damage dealt.
