This angel is meant to be a servant of the 7 Gods of Law in my ACKS Dwimmermount game. There is an Empyreal in the Dwimmermount new monsters, but they're a bit too strong and busy for the way I'd prefer a game to go. Plus, my party is mostly Chaotic... one of the characters is a Chaotic Empyrean cleric. I expect I will be enforcing an alignment change on him soon, as he definitely plays more Lawful.

An empyreal is a powerful servant of the Empyrean Gods, resembling a 9' tall, human of noble mien, dressed in the finest plate, bearing a flaming silver sword and long, mirror-polished shield. Upon their back they bear four wings of purest white. They are hot-tempered and forceful, but always fair and just in their dealings with other beings. Empyreals can innately tell the alignment of a creature they fix their gaze upon, and judge them accordingly.
When an Empyreal attacks with it's mighty sword, it deals 1d6 damage to Lawful foes, 2d6 to Neutral foes, and 3d6 to Chaotic foes.
Chaotic-aligned creatures within 60' of an Empyreal suffer a -1 to attack and saving throws, and suffer 1d4 points of damage per round from the searing weight of divine judgment. Lawful allies of an Empyreal within 60' instead gain a +1 to attack and saving throws. An Empyreal is able to cast spells as a 7th level cleric.
Empyreals are immune to acid, fire, petrification and mortal poisons. They suffer only half damage from electricity and ice.
