Electrified Body. Any creature that touches the hybrid or hits it with a melee attack while within 5 feet of it takes 5 (1d10) lightning damage.
Illumination. The hybrid sheds bright light in a 10-foot radius and dim light for an additional 10 feet.
Multiattack. The hybrid makes two attacks: one with its shocking touch and one with its tentacles.
Shocking Touch. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 9 (2d8) lightning damage.
Tentacles. Melee Weapon Attack: +4 to hit, reach 15 ft., one creature. Hit: The target is grappled (escape DC 11), and the hybrid pulls the target up to 15 feet straight toward it. Until this grapple ends, the target takes 5 (1d10) lightning damage at the start of each of its turns, and the hybrid shocker can't use its tentacles on another creature.
