Bloodletter's Curse
Patch 7.2Base Stats
- Cost: 2900g
- Recipe: Sorrow Mask (1300g) + Fiendish Codex (900g) + 700g
- AP: +65
- Max HP: +350
- Ability Haste: +15
Vile Decay
- Dealing magic damage to a champion with an ability or passive reduces their MR by 7.5% for 6s, stacking up to 30%.
- The MR reduction also helps your allies' magic damage, so in a composition with several mages or an AP jungler it effectively raises the whole team's output. Reaching the 30% cap takes four applications, which favours champions with damage over time or area abilities that connect repeatedly. The 350 max HP keeps you standing while you hold a forward position and keep casting. It is a poor fit for a mage who wants one big burst.
