Nether Grasp is a channeledtether-like damage over time ability. While in range of the tether the target takes magic damage every 0.5 seconds. Both the suppression and tether are removed if the channel is stopped or interrupted.
Possible Bug:Ragnarok will remove both the suppression and the tethered damage as well as prevent Malzahar from even forming the tether if Ragnarok is already active (effectively putting Nether Grasp on cooldown with no effect)
Like all channeled abilities, Nether Grasp will be interrupted by hard crowd control (stun, silence) and will end prematurely if Malzahar performs any other action (moving, casting other abilities)
If Malzahar has not taken damage nor been affected by crowd control in the last 23 - 6 (based on level) seconds, he phases out, which lingers for 1 second after taking damage or blocking a crowd control effect. While phased out, Malzahar is immune to crowd control effects and takes 90% reduced damage. Damage from minions does not interact with Void Shift.
Malzahar spawns a Voidling at the target location, which lasts for 12 seconds. The first time a Voidling attacks a champion or large monster, or assists in killing a unit, Malzahar will spawn an additional Voidling with the same remaining duration that can in turn spawn an additional Voidling. This cannot happen if there is less than 4 seconds remaining. When three or more Voidling are active, they all gain 50% bonus attack speed.
Voidlings deal 30 / 32.5 / 35 / 37.5 / 40% AD physical damage plus 10 / 15 / 20 / 25 / 30 (+ 10% AP) bonus magic damage. The damage is reduced to 75% against monsters, and increased to 300% against minions below 25% of their maximum health.
Voidlings will gain 100% bonus movement speed toward priority targets (denoted with †)
