Actions

Electrified Bite.

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage plus 7 (2d6) lightning damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be grappled (escape DC 13). A creature grappled by the defender takes the damage again at the start of each of the defender's turns. The defender can have only one creature grappled in this way at a time, and the defender can't make Electrified Bite attacks while grappling.

Bonus Actions

Light Beam.

The defender emits bright light from its eyes in a 60-foot cone, or it shuts off this light.
