Multiattack

The clockwork archon makes two attacks with its transforming weapon.

Transforming Weapon

Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 29 (4d10 + 7) bludgeoning or slashing damage. As a bonus action, the archon can change its weapon from a sword to a hammer or vice versa, allowing it to change its damage between bludgeoning and slashing.

Fire from Heaven (Recharge 5-6)

The clockwork archon unleashes a brilliant beam in a 90-foot line that is 10-feet wide. Each creature in that line must make a DC 17 Dexterity saving throw, taking 58 (13d8) radiant damage on a failed save, or half as much damage on a successful one.
