Screenshots

Start with the PoB build code linked in the issue and reproduce the interaction between Grace, the Precursor's Emblem modifier, Iron Reflex, and frenzy-charge state. Trace the entry point that evaluates conditional item effects and verify that the keystone is inactive below maximum charges and active at maximum charges; confirm the resulting armour and evasion values.
