Challenge 3 (700 XP)

Disguise. The xenabsorber has advantage on Charisma (Deception) checks to pass itself off as the type of creature it is impersonating as long as it has at least 1 trait from that creature.

Trait Mimicry. As a bonus action, a xenabsorber can take on 1 nonmagical physical trait, attack, or reaction of a beast or humanoid with a challenge rating equal to or less than its own that it has seen within the last week (see Trait Mimicry sidebar). It can have up to 5 such traits at a time, no more than two of which can be attacks. Each trait lasts until the xenabsorber replaces it with another trait as a bonus action. If the xenabsorber goes a week without exposure to a single beast or humanoid, it loses all of its traits and reverts back to its true, blue crystalline form.

Actions

Multiattack. The xenabsorber makes two melee attacks.

Slam. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 3) bludgeoning damage.
