Angel

The Angels are mini-bosses that can appear most commonly in Angel Rooms. There are two angel variants: Uriel and Gabriel.

Locations

A random angel appears when destroying an angel statue in an Angel Room with an explosion or similar effects.
Dark "fallen" versions of both angels show up during the battle against Mega Satan.
- Fallen Uriel has 450 health instead of 400.
- Fallen Gabriel has 750 health instead of 660.
Uriel appears after the 9th sacrifice and Gabriel appears after the 11th sacrifice in a Sacrifice Room.
Both angels have a chance of appearing in Boss Rush, though it does not drop a Key Piece on death.
Angel Statues can sometimes appear in Super Secret Rooms, and I AM ERROR rooms.
There's a small chance for an angel statue to replace the Satan statue in the Devil Room.

Notes

The angels will always alternate in order of appearance. Thus, if Uriel has just been defeated, the next angel spawn is guaranteed to be Gabriel and vice versa.
If the player defeats an angel and they already have both Key Pieces, no Key Piece drops. However, if this occurs, it counts as a normal room clear, and the player may be rewarded with a pickup or chest.
- Likewise, if an angel is killed in Chapter 1, No parts of the key are dropped. This only happens when the angel statue is spawned in a Secret Room in Chapter 1.
Angels only drop a Key Piece the first time they are defeated, even if Isaac does not pick up the Key Piece, subsequent kills in the same run provide no pedestal item rewards.
- Angels will drop a Key Piece even if they were defeated before. Additionally, if Isaac has one of the Key Pieces, angels will always drop the other piece, even if he already skipped that piece or that particular angel normally wouldn't drop it (for instance, Uriel will drop Key Piece 2 if Isaac already has Key Piece 1 from fighting him earlier).
Rerolling Key Piece 1 or Key Piece 2 will yield an item from a pool, depending on which room the Key Pieces are in.
- Rerolling the Key Pieces in an Angel Room will yield an item from the Angel Room item pool.
The hitbox for the angel's beams of light are off and causes Isaac to take damage if he is anywhere near them, even if he does not touch the beam.
Angels will drop items from the Angel Room item pool instead of the Key Pieces if Isaac is holding Filigree Feather.
Sometimes, two angel statues can appear in the same room. Destroying both at the same time will spawn both Uriel and Gabriel, but only one Key Piece will drop. If each angel is spawned and defeated separately, both will drop Key Pieces.
- Both angels will drop key pieces if fought at the same time in Repentance.
Uriel and Gabriel are immune to the Fear effect.
When spawned inside a Sacrifice Room, the room is not locked, allowing Isaac to simply walk out of the fight.
- When returning to the Sacrifice Room, the angel will be gone.
- As a result, it is possible to miss obtaining Key Piece 1 while getting Key Piece 2.
Both Angels will do a full heart of contact damage, regardless of the chapter.

Trivia

Uriel (or Auriel/Oriel) is one of the archangels of post-Exilic Rabbinic tradition, and also of certain Christian traditions. The name means "God is my light" - in Hebrew, ori (or uri) means "my light" and el means "god".
Gabriel is an archangel who typically serves as a messenger sent from God to certain people in Abrahamic religions. The name means "God is my strength".
Uriel and Gabriel, along with the angel statues, have no face. This is in reference to Exodus 33:20 in the Bible.
- "But," He said, "you cannot see my face, for man shall not see me and live."
Uriel and Gabriel may be based on Seraph and Cherub angels. Seraphim are angels that fly above God’s throne while Cherubim guard the throne.
