This spell makes your eyes glow blue and allows you to see magical auras within 120 feet of you. These magical auras surround magic items and other sources or conduits of magic such as other spellcasters.

You know the location and power of all magical auras within your range of this spell. An aura's power depends on a spell's level or the effect that the magic item produces (the rarer the item, the stronger the aura produced). If an item or creature bearing an aura is within 120 feet of you, you know the school of magic involved in each object and the maximum spell slot level the item or creature can produce.

If you focus on an object, you can determine what that object can do as per the identify spell. If you focus on a creature, you can determine if that creature has a spellcasting feature such as a lich or other magical abilities such as a quasit's ability to turn invisible. To do so, you must succeed on an Intelligence (Arcana) skill check with a DC of 10 + the following depending on the object's rarity: +2 for a common item, +4 for an uncommon item, +6 for a rare item, +8 for a very rare item, +10 for a legendary item and +15 for artifacts. For a creature, the DC is equal to 10 + the creature's highest level spell slot or the creature's CR; whichever is higher. Any creature with a CR of less than 1 is treated as having a CR of 0 when determining the DC of the Arcana skill check.
