Actions
Tubes. Melee weapon attack: +3 to hit, one creature. On hit: 2d8+1 piercing damage and if the target is small or larger, the changeling attaches to it. While attached this way, the changeling's speed becomes zero and it moves along with the creature. Any creature including the one the changeling is attached to can use its action to make a DC 13 STR (Athletics) check to remove the changeling, or the changeling can use its action to detach itself.

Control. The changeling attempts to gain command of the creature it is attached to. The target must make a DC 13 CHA saving throw. On a failure, the changeling chooses either the movement, attack action, or bonus action that the target takes on its next turn. On the 5th consecutive failure the changeling enters and takes full command of the target.
