Traits
Magic Resistance. The steel predator has advantage on saving throws against spells and other magical effects.
Unusual Nature. The steel predator doesn't require air, food, drink, or sleep.
Actions
Multiattack. The steel predator makes one Bite attack and two Claw attacks.
Bite. 12 to hit, reach 5 ft., one target. Hit: 18 (2d10 + 7) lightning damage.
Claw. 12 to hit, reach 5 ft., one target. Hit: 16 (2d8 + 7) force damage.
Stunning Roar (Recharge 5+). The steel predator emits a roar in a 60-foot cone. Each creature in that area must make a 19 Constitution saving throw. On a failed save, a creature takes 33 (6d10) thunder damage, drops everything it's holding, and is stunned for 1 minute. The stunned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. On a successful save, a creature takes half as much damage and isn't stunned.
