Morphed weapon. The changeling can form a physical weapon (blade, spike, club) with one of its limbs as a free action. The weapon does slashing, piercing, or blunt damage (changeling's choice).
Regeneration. Changelings regenerate 1d6 HEALTH, physically repairing damage, at the start of each turn as long as they are still alive.
Shape changer. Changelings can change shape to accurately resemble any other medium-sized object or creature. The result its 100% accurate in physical appearance, although the changeling may need to rely on bluffing skills when interacting with others. Some changelings spend years in a borrowed shape. Changing shape takes all of the changeling's actions.
