Tome of the Reaper
+240 Ability Power
+500 Max HP
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.
Overall good item, although somewhat unpopular. A lot of ability power, equal to Boomstick and second only to Holy of Holies. It's passive is the same as that of Curse of Death in attack section. 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). Also items like Crimson Banner and Gaia's Standard.
