Critical Mind
Boosts Emma's and Koo's critical rate by 1.1x/1.2x/1.3x/1.4x/1.5x while Emma is recovering HP. Every Spirit Stone carries two things at once: a stat boost — here Max Defense: 15 — and an effect, and both scale with the stone's rank rather than with anything you do to it.

When to use it
A multiplier rather than an addition, which no other critical source on this site uses — so it scales with the Critical Charms rather than stacking flatly with them. "While recovering HP" presumably means during passive regeneration, which the hunger system gates, but no source says so.
Where it sits in the gear catalogue
- Its stat half is a Defense ceiling of 15, which is the first-highest of the two Defense ceilings among the 33 Spirit Stones catalogued here. The rest of that group: Iron Wall (9).
- 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.
