  • Multiattack. The firestorm giant makes two Obsidian Axe or Firestorm Bolt attacks.
  • Obsidian Axe. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 19 (3d8 + 6) slashing damage plus 3 (1d6) cold damage and 3 (1d6) fire damage.
  • Firestorm Bolt. Ranged Spell Attack: +6 to hit, range 120 ft., one target. Hit: 13 (3d6 + 3) fire damage plus 10 (3d6) cold damage.
  • Lava Geyser (Recharge 5–6). The firestorm giant gestures at a point on the ground it can see within 60 feet of it. A fountain of molten rock erupts from that point in a 10-foot-radius, 40-foot-high cylinder. The area is difficult terrain for 1 minute. Each creature in the cylinder must make a DC 16 Dexterity saving throw. On a failure, a creature takes 24 (7d6) fire damage and is coated in hardened lava.


Firestorm giants dwell on the frozen glaciers of the Northlands where their migrations follow subterranean ley lines. Most of the clans view the God of the North Wind as a perversion of the natural order, actively working against Boreas and his frost giant clans. A few follow Loki as a figure of conjoined frost and flame, rather different than the human view.

The huge giant with a wedge-shaped head snarls and extends a hand. A geyser of molten lava bursts out from the ground as the gesture ends.

Firestorm giants originated with the rare offspring of a frost giant and a fire giant. Now their own people, firestorm giants maintain their distance from both sides of their heritage, living and celebrating their own unique culture.

Quake Walkers. Firestorm giants dwell in cold and arctic climates, and they instinctively follow fault lines and glacial valleys as their clans migrate. Occasionally, a clan settles near a volcano or large hot spring.

Natural Protectors. The fire and ice swirling through firestorm giants’ veins war constantly within them, and they find solace in the rhythmic chaos of the natural world, particularly geologically active areas. Because of this, they viciously protect nature from destruction and despoilment. They harbor a deep hatred of magical winters, poisonous mine waters, dam construction, and other disruptions to nature.

Unexpected Hospitality. Firestorm giants understand the dangers of their arctic and volcanic homes and are often sympathetic to outsiders braving such dangers. Their sympathy and hospitality last only so long as the outsiders don’t cause magical or unnatural disruptions to the giants’ homes.
