A shadow rat can, as a standard action, assume an incorporeal form for up to 1 hour per day. In this form, the shadow rat loses its natural AC bonus but gains a +2 deflection bonus to AC. While in this form, the shadow rat is AC 16 (+2 deflection, +2 Dex, +2 size), touch 15, flat-footed 13. The shadow rat can still attack corporeal opponents while in its incorporeal form, but its attack only inflicts Strength damage and cannot cause physical damage. The shadow rat gains the incorporeal subtype while using this ability.
A shadow rat can disappear into the shadows as a move action, gaining total concealment in all levels of illumination save bright light.
