Metagross (5e Creature)
From D&D Wiki
Medium construct, any alignment
Immutable Form. The metagross is immune to any spell or effect that would alter its form.
Dual Mind. The metagross has advantage on Wisdom saving throws.
Magic Weapons. The metagross's weapon attacks are magical.
Clear Body. The metagross is immune to any effect that would cause it to gain disadvantage on attack rolls, ability checks, or saving throws.
Multiattack. The metagross makes two hammer arm attacks.
Hammer Arm. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 20 (4d6 + 6) bludgeoning damage.
Meteor Mash (Recharge 5-6). The metagross summons four enormous masses of rock to crash into the ground in four places within 120 feet of it. Each creature in a 20-foot-radius sphere centered on each point it choose must make a DC 18 Dexterity saving throw. The sphere spreads around corners. A creature takes 35 (10d6) bludgeoning damage on a failed save, or half as much damage on a successful one. A creature in the area of more than one meteor is affected only once. The meteors damage objects in the area.
Light Metal. When the metagross takes damage from a melee attack, it can reduce the damage by 7 (2d6) and be pushed back 5 feet to an unoccupied space if one is available.
