Relentless (Recharges after a Short or Long Rest). If Gorthok takes 27 damage or less that would reduce it to 0 hit points, it is reduced to 1 hit point instead.
Multiattack. Gorthok makes two melee attacks: one with its lightning tusks and one with its thunder hooves.
Lightning Tusks. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 12 (2d6 + 5) slashing damage plus 7 (2d6) lightning damage.
Thunder Hooves. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 12 (2d6 + 5) bludgeoning damage plus 7 (2d6) thunder damage.
Lightning Bolt (Recharge 5–6). Gorthok shoots a bolt of lightning at one creature it can see within 120 feet of it. The target must make a DC 15 Dexterity saving throw, taking 18 (4d8) lightning damage on a failed save, or half as much damage on a successful one.
