Incorporeal A shadow has no body and can pass through physical objects, though it can't end its turn inside one. Most checks that use Strength and require a body, such as Grapple and Shove, don't work against a shadow, and a shadow can't use them.

Light Vulnerability A weapon with a light spell cast on it gains the magical trait when used to attack the shadow.

Slink in Shadows The shadow can Hide or end its Sneak in a creature's or object's shadow.

Steal Shadow [>] (divine, necromancy) If the shadow hit a living creature with a Strike on its previous action, it can use this action to pull at the target's shadow, imposing a –1 status penalty to Athletics and to attack rolls and damage rolls that use Strength. The penalty increases each time a shadow uses this ability to a maximum of –4. The penalty decreases by 1 every hour.
