DEATHFIRE'S HAND [AP Assassin's Duskblade]
#DEATHFIRE'S HAND +80 AP +5% movement speed +10 Magic Penetration
Unique Passive: Your single-target spells and auto-attacks mark enemy champions for 2 seconds. If you damage a marked enemy within the duration of the mark you apply Accursed Touch. (120 second cooldown).
Unique Passive [Accursed Touch]: After 2 seconds deal the target magic damage equal to 90 + 25% of the target's missing health. If the target dies before Accursed Touch deals damage, the full cooldown of the application is refreshed.
Appealing to burst mages with single-target abilities (LeBlanc, Ahri [charm only], Katarina [E and probably the primary Q target], Fizz, Diana, Kassadin, Ekko), this is designed to give AP assassins a similar tuning lever to AD assassins.
An alternative might by this:
Unique Passive: Your single-target spells apply Accursed Touch* to enemy champions (120 second cooldown).
Unique Passive [Accursed Touch]: For 3 seconds your spells deal +30% damage to the target. If the enemy champion is slain during this time the cooldown resets, but that champion is immune to further applications for 120 seconds.
The second option might give it more distinction from Duskblade, and provide more levers to tweak the effect.
