Crystalis Auralius

Umber Camouflage. The octopus has advantage on Dexterity (Stealth) checks made while lightly obscured.

Beckoning Light. The crystals on the octopus' back emit dim light in a 10 foot radius.

Earth Unbound (2/Day). The octopus can innately cast the levitate spell once with this trait, requiring no material components. When the spell is cast in this way, it does not require concentration.

Tentacles. Melee Weapon Attack: +5 to hit, reach 15 ft., one target. Hit: 10 (2d6 + 3) bludgeoning damage. If the target is a creature, it is grappled (escape DC 16). Until this grapple ends, the target is restrained, and the octopus can't use its tentacles on another target.

Luminous Spores (Recharges after a Short or Long Rest). A 20-foot-radius cloud of radiant glowing spores extends all around the octopus as if it were underwater. The area is heavily obscured for 1 minute, although a significant wind can disperse the spores. After releasing the spores, the octopus can immediately use the Dash action as a free action.

Paralyzing Bite (3/Day). Melee Weapon Attack: +5 to hit, reach 5 ft., one target grappled by the creature. Hit: 10 (2d6 + 3) piercing damage, and the target must make a DC 11 Constitution saving throw, taking 12 (3d8) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.

Crystalline Refraction. If the octopus makes a successful saving throw against a spell, or a spell attack misses it, the octopus can choose another creature (including the spellcaster) it can see within 30 feet of it. The spell targets the chosen creature instead of the octopus. 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.
