Critical Damage Increase
Boosts Emma and Koo's Critical Damage by 5%/10%/15%/20%/25%. Every Spirit Stone carries two things at once: a stat boost — here Max HP: 80 — and an effect, and both scale with the stone's rank rather than with anything you do to it.

When to use it
The plainest stone in the set and one of the best stat halves. Note that Critical Damage and Critical Rate are different things here — the Critical Charms raise the rate, this raises the damage, and no source publishes the base value of either.
Where it sits in the gear catalogue
- Its stat half is a HP ceiling of 80, which is the fourth-highest of the seventeen HP ceilings among the 33 Spirit Stones catalogued here, level with Dark Approach. The rest of that group: Momentum (102), Stone Mind (90), Homing Shots (90), Transcendent Bloom (69), Entanglement Increase (65), Empowered Headshots (65), Faster Reloads (65), Infernal End (65), Fortification (57), Final Infusion (54), Well of Fortitude (48), Sharpshooter (39), Entangled Assassination (39), Break Recovery (39) and Entanglement Stone (33).
- 25 of the 33 stones point at the same system as this one — How Spirit Stones work — ranks, why the published figure is a ceiling, and duplication — which is where the rank arithmetic behind every figure above is worked out.
