Lava Bound.

The magma octopus can exist outside of lava for up to 1 hour each day. If it remains outside of lava for 1 minute or longer, its skin begins to dry and harden like rapidly-cooled magma. While its skin is hardened, it has a walking speed of 20 feet, an Armor Class of 18, and vulnerability to cold damage. If it remains outside of lava for 1 hour or longer, it becomes petrified, transforming into basalt. Its body returns to normal if it is submerged in lava for 1 round.
Lava Swimmer.

While in lava, the magma octopus has a swimming speed of 60 feet and can move through the lava as if it were water.

Actions

Multiattack. The magma octopus makes four attacks with its tentacles.
Tentacle. Melee Weapon Attack: +8 to hit, reach 15 ft., one target. Hit: 8 (1d6 + 5) bludgeoning damage plus 2 (1d4) fire damage. If the target is a creature, it is grappled (escape DC 16). Until this grapple ends, the target is restrained, and it takes 2 (1d4) fire damage at the start of each of its turns. The magma octopus can grapple up to two targets at a time.
Magma Blast (Recharge 6).

The magma octopus sprays magma in a 30-foot cone. Each creature in that area must make a DC 16 Dexterity saving throw, taking 28 (8d6) fire damage on a failed save, or half as much damage on a successful one. If a creature fails the saving throw by 5 or more, it catches fire. Until someone takes an action to douse the fire, the creature takes 5 (1d10) fire damage at the start of each of its turns.
