Sanctum Archangels can guard to resist damage, but while guarding, it cannot attack. As they appear in groups, the player can concentrate on the others if one is guarding.
They can be quickly staggered and launched in the air, but the player can't launch the Archangel if it is guarding. Its attack can easily interrupt the player's actions, and Vigilance hardly makes a difference, so it'd be easier to focus on attacking them while they aren't guarding.
archangel is an angel of high rank. Beings similar to archangels are found in a number of religious traditions, but the word "archangel" is usually associated with Abrahamic religions. The word is derived from the Greek ἀρχάγγελος (arch- + angel, literally chief angel).An
