Mithral Tortoise (5e Creature)
From D&D Wiki
Huge beast, unaligned
Skills Perception +5
Amphibious. The tortoise can breathe air and water.
Multiattack. The tortoise makes two attacks: one with its bite and one with its stomp.
Bite. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 22 (3d10 + 6) piercing damage.
Stomp. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 19 (3d8 + 6) bludgeoning damage.
Reflective Shell. If the tortoise makes a successful saving throw against a spell, or a spell attack misses it, the tortoise can choose another creature (including the spellcaster) it can see within 30 feet of it. The spell targets the chosen creature instead of the tortoise. If the spell forced a saving throw, the chosen creature makes its own save. If the spell was an attack, the attack roll is rerolled against the chosen creature.
Mithral tortoises, also called mithral shells or mithral turtles, are gigantic turtles that crush foes beneath their fearsome weight. Late in its lifetime, a mountain beast is compelled to travel deep underground and gorge itself on stones and ores, particularly mithral. As it eats, the metal is slowly absorbed into the creature's shell, granting it tremendous protection from attackers. The unusual composition of the creature's shell also allows it to reflect magical energy, though the tortoise must position itself very precisely to do so.
