Unstable Transfusion
⭐ RARITY: UNCONFIRMEDCommunity sources disagree on rarity (Common vs. Uncommon). Until an official note clarifies it, we list it as Unconfirmed. Gameplay effect is consistent across sources.
🧪 What Bloodmark Does
Unstable Transfusion introduces the Bloodmark status. Each hit has a 27% chance to add a stack; more stacks = faster melts on elites and bosses. It’s especially potent in builds that hit rapidly or constantly apply contact damage.
Key Takeaways
- Fixed on-hit chance: 27% per hit.
- Stacks up to high values and dramatically improves time-to-kill on tough targets.
- Best with multi-hit / high attack-speed weapons and lifesteal/regen to stay healthy while you stack.
