At will: counterspell, dispel magic

Multiattack. Balthazar makes three Claw attacks. He can replace one attack with Diabolic Chains or Incinerate if he has the Soul Charges to do so.

Claws. Melee Weapon Attack: +16 to hit, reach 5 ft., one target. Hit: 21 (3d8 + 8) slashing damage plus 14 (4d6) fire damage.

Igniting Spark. Ranged Spell Attack: +18 to hit, range 60 ft., one target. Hit: 18 (4d8) fire damage, and a Hellfire Surface forms in a 5-foot radius beneath the target.

Incinerate (2 Soul Charges). Each creature in a 10-foot-radius, 40-foot-high cylinder within 100 feet must make a DC 26 Dexterity saving throw, taking 45 (10d8) fire damage on a failed save, or half as much on a success.

Diabolic Chains (2 Soul Charges). Balthazar lashes three hellfire chains at up to three targets within 60 feet, making a separate +18 ranged spell attack against each. Hit: 24 (7d6) fire damage, the target is pushed 10 feet away, and a Hellfire Surface forms in a 5-foot radius beneath it.

Igniting Spark (1 Soul Charge). Balthazar uses Igniting Spark as a bonus action. Creatures within the resulting Hellfire Surface are afflicted with Roiling Hellfire, taking 28 (8d6) fire damage at the start of each of their turns until they leave it.

Opportunity Attack. When a creature Balthazar can see moves out of his reach, he makes one Claw attack against it.

Counterspell. When a creature within 60 feet that Balthazar can see casts a spell, he casts counterspell in response. Balthazar can take this reaction once on each creature's turn, even if he has already used his reaction this round. If the triggering spell is 4th level or higher, he makes an ability check of +10 against a DC of 10 + the spell's level.
