Finestrike — Bloodborne
Finestrike — Blood gems, Bloodborne. Take advantage of windows while the target attacks or recovers from an attack.

The condition to recognise
This bonus activates on a counterattack: hit the enemy during its attack or immediately afterwards, during recovery. A target that is merely standing still is not necessarily vulnerable to this effect.
Value and availability
| Effect | Table value |
|---|---|
| Attack against an open foe | +0,4 % à +13,5 % |
Choose your moves
Look for range and speed that let you hit during the opponent's window. This effect normally appears as a secondary effect; the wiki notes a dedicated radial in the expansion. You therefore need to compare the gem's primary effect too.
Gem effects and acquisition

Hit the target during that window; a target that is merely standing still is not necessarily open.
