Volkhan the Flameborn

Spellcaster. Volkhan is an 8th level spellcaster, capable of multiple cantrips and fire-based evocation and abjuration spells.

Multiattack. The giant makes three greatsword attacks.

Greatsword. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 28 (6d6 + 9) slashing damage.

Flame Strike. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 28 (6d6 + 9) fire damage.

Hellish Rebuke. Volkhan parries your attack and snaps his enormous fingers, and you are momentarily surrounded by hellish flames. The attacker must make a Dexterity saving throw, DC18. It takes 2d10 fire damage on a failed save, or half as much damage on a successful one.

Counterspell. Volkhan attempts to interrupt a target in the process of casting a spell. If the creature is casting a spell of 3rd level or lower, its spell fails and has no effect. If it is casting a spell of 4th level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell’s level. On a success, the creature’s spell fails and has no effect. Volkahn must be within 60 ft. of the spellcaster.

Volkhan has 4 legendary actions.

Flare. Volkhan releases a burst of flames around him in a 30ft radius. Anyone caught in the flames must make a DC15 DEX save or take 3d10+10 damage.

Healing Blaze. Volkhan bathes a wound in one of the torches in his lair. The wound seems to cauterize and then heal for 2d10+5 HP.

Scalding Metal. Volkhan heats up the metal within a 10ft radius of him. Those holding metal objects or wearing metal armor must make a DC15 Con Save to hold onto their equipment, and to take half damage of 3d10.
