Dab [>] (enchantment, manipulate, mental, occult) Requirements The blood painter is within reach of an enemy taking persistent bleed damage; Effect The blood painter touches the creature and applies blood to one of their four claws; the blood remains fresh for 1 minute. The target must succeed at a DC 28 Will save or become fascinated with the blood painter.

Paint [>] (concentrate, illusion, manipulate, occult) Requirements The blood painter has fresh blood applied to a claw using Dab; Effect The blood painter expends the blood on one claw to paint a illusion with the effects of one of the following spells: illusory creature, illusory disguise, illusory object, or mirror image. The Paint action gains the traits of the spell it's reproducing, and the blood painter can Sustain a Spell on these effects. They use a spell attack modifier of +20 and DC 28 for these effects, which are heightened to 5th level. If they have fresh blood applied to two or more claws, the blood painter can expend the blood on all of them to instead produce the effects of cloak of colors or vibrant pattern. Any effects produced by this ability have a +2 status bonus to attack rolls, damage rolls, saving throws, skill checks, and AC against the creature whose blood was used to Paint and that creature takes a –2 status penalty to Perception checks and saves against it.
