Fire Giant

Giant Attributes. The fire giant is resistant to the stunned condition, and it is vulnerable to the prone condition.

Multiattack. The fire giant makes two Flaming Greatsword or Lava Boulder attacks.

Flaming Greatsword. _Melee Weapon Attack:_ +11 to hit, reach 10 ft., one target. _Hit:_ 28 (6d6+7) slashing damage plus 4 (1d8) fire damage.

Lava Boulder. _Ranged Weapon Attack:_ +7 to hit, range 60/240 ft., one target. _Hit:_ 19 (3d10+3) bludgeoning damage plus 13 (3d8) fire damage.

Volcanic Burst (Recharge 5-6). The fire giant expels built-up heat from within itself, sending a blast of lava outward. Each creature within 15 feet of the fire giant must make a DC 16 DEX save. On a failure, a creature takes 36 (8d8) fire damage and is knocked prone. On a success, a creature takes half the damage and isn't knocked prone. A creature that fails this save has disadvantage on the next save it makes against the giant's Pyroclastic Surge before the start of the giant's next turn.

Pyroclastic Surge. A burst of volcanic gas and rock fragments flows in a 60-foot-line that is 5 feet wide from the fire giant's outstretched hand. Each creature in the line must succeed on a DC 16 DEX save or be poisoned until the end of its next turn and pushed up to 15 feet away from the giant. A creature that fails the save by 5 or more is petrified in volcanic ash for 1 hour or until a creature spends 1 minute soaking the petrified creature in cool water.
