Advanced Maneuver Grab and Sting
Grab and Sting

Become Shadow (shadow, transmutation) The shadow familiar transforms its body into barely tangible shadow. It gains resistance to all damage (except force) equal to half your level but can't use any actions requiring a physical form. The familiar can also slip through gaps at least 2 inches wide, or 1 inch wide if it Squeezes. It can use this action again to return to its normal form. This action has the trait matching your tradition of magic, or occult if you aren't a spellcaster.
Slink in Shadows The shadow familiar can Hide or end its Sneak in a creature's or object's shadow.
Steal Shadow (necromancy) Frequency once per 10 minutes; Effect The shadow familiar makes a melee attack with an attack roll modifier equal to your spell attack roll modifier. If the Strike is successful, the target is enfeebled 1 and its shadow disappears. After 24 hours, the enfeebled condition ends, and they regain their shadow once more. Any effect that reduces or removes the enfeebled condition restores their shadow as well. This action has the trait matching your tradition of magic, or occult if you aren't a spellcaster.
