Atlas's Adversary Analysis

Choose one creature you can see within range. They must make a Wisdom Saving Throw. On a failed save, you learn if the creature is an Aberration, a Beast, a Celestial, a Construct, a Dragon, an Elemental, a Fey, a Fiend, a Giant, a Humanoid, a Monstrosity, an Ooze, a Plant or an Undead. Additionally, you learn if the creature has any Immunity, Resistance and/or Vulnerability, as well as which they are.

Also, this Spell sees through the Mask effect of the Nystul's Magic Aura spell.
