Curse of Death
+100 Attack Damage
+10% Life Steal
On dealing damage, reduces target's HP regeneration by 50% for 1.5 seconds. If this is triggered by normal attacks, the duration is extended to 3 seconds.
No use in any specific build, but has a great utility against some champions like Thane, Peura, Lu Bu, Kil'Groth, Taara, Butterfly, Maloch, Arduin and certain items that restore hp, like any life stealing item (Beast in particular).
