Because Blood Mimics are made from blood of a Vampire, their sight can map out the systems of blood of any living creature, but only see vague shadow outlines of undead, constructs, vampires, etc. that cannot bleed. Blood Mimics rely on Blood Sight in order to alter themselves biologically to map the complete copy of the target they take the form of. Perception checks are often given with disadvantage cause of this regarding non-living creatures, but are given advantage with those alive.

Do to the amorphous nature of your true form, you cannot benefit from armor, though you can use a shield. Your Armor Class is equal to 11 + your Dexterity modifier and you are immune to the prone condition.

Your maw is a natural weapon, which you can use to make unarmed strikes. If you hit with it, you deal piercing damage equal to 1d6 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.

Because of your existence as bile of vampiric blood, you are neither needed to satiate nor are you without need of blood from mortals. Instead, as a Blood Mimic, you are able to unlock a series of feats and innate strengths each time you drain a target of their blood into your ooze. The target must be dead but not rotting, and each time their entire blood stream is tapped, a DM will roll a 1d100 chance die on the ability, feat, or advantages you may gain from the person you drained.

You gain innately still the Grappler, Shapeshifter, and Monstrosity feat
