Dirty — Bloodborne
Dirty — Blood gems, Bloodborne. Read the status buildup, then choose a target whose resistance allows it to trigger.

What the number measures
The value adds poison buildup; it is neither a damage percentage nor an amount of HP removed per hit. The status must reach the target's resistance threshold to trigger.
Before dedicating slots to poison
- Check resistance to the correct poison, slow or rapid, on the boss page for the selected context.
- Immunity makes the setup useless against that target. High resistance may require too many hits to justify losing direct damage.
- Compare buildup speed with the weapon and moves you actually use.
