The Guardian Angel
See that you despise not one of these little ones: for I say to you, that their angels in heaven always see the face of my Father who is in heaven. (The Gospel According to St. Matthew 18:10)
Not all angels are celestial agents “sent forth into the planes to further” some god’s agenda for weal or woe. Not all angels “are destroyers”. The guardian angel’s task is simple: to protect some mortal from harm. Most often, the guardian angel watches over a child. The guardian angel spends much of its time observing both unseen and unheard its charge. When it needs to intervene, it does so carefully so as to have the least direct influence on events. This does not mean the guardian angel cannot take direct action when necessary. While it lacks the power of, say, the deva, the guardian angel is not a foe to be trifled with lightly.

Angelic Weapons. The guardian angel’s weapon attacks are magical. When the guardian angel hits with any weapon, the weapon deals an extra 3d8 radiant damage (included in the attack).
Innate Spellcasting. The guardian angel’s spellcasting ability is Charisma (spell save DC 15). The guardian angel can innately cast the following spells, requiring only verbal components:
* At will: detect evil and good, detect poison and disease, sanctuary
* 1/day: dispel evil and good
Magic Resistance. The guardian angel has advantage on saving throws against spells and other magical effects.
Actions
Multiattack. The guardian angel makes two attacks using its spear, or one attack with its fire bolt.
Holy Fire. Ranged Spell Attack: +7 to hit, range 120 ft. Hit: 27 (6d8) fire damage plus 13 (3d8) radiant damage.
Spear. Melee or Ranged Weapon Attack: +6 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 6 (1d6+3) piercing damage plus 13 (3d8) radiant damage, or 7 (1d8+3) plus 13 (3d8) radiant damage if used with two hands to make a melee attack. As a bonus action, the guardian angel can teleport the spear back to its hand. It can do this in between attacks with the spear.
Superior Invisibility. The guardian angel magically turns invisible (as invisibility but requiring no concentration). Any equipment the guardian angel wears or carries is invisible with it. While invisible, the guardian angel has advantage with Stealth checks.
Maybe we can update angels’ (and as a result, the fiends) stats in 5E with the notes you took on improving Pathfinder angels with medieval theology. It would certainly change the game and player expectations for the upcoming Saturday game.
