An ooze affected by a desiccate is surrounded in a pale nimbus of mystic energy imbued with the drying properties of salt. This energy has little effect on most cuts and injuries, but can seep into the ooze when it is struck by a particularly well‑placed or deep blow, causing the ooze to dry out, flake and crack. This makes the ooze vulnerable to critical hits and precision damage (such as sneak attack) for the duration of the spell.
