This spell makes your eyes glow blue and allows you to see magical auras within 120 feet of you. The effect is similar to that of a [_detect magic_](/spells/detect-magic) spell, but _arcane sight_ does not require concentration and discerns aura location and power more quickly. You know the location and power of all magical auras within your sight. An aura's power depends on a spell's functioning level or an item's caster level, as noted in the description of the [_detect magic_](/spells/detect-magic) spell. If the items or creatures bearing the auras are in line of sight, you can make Spellcraft skill checks to determine the school of magic involved in each. (Make one check per aura; DC 15 + spell level, or 15 + half caster level for a nonspell effect.) If you concentrate on a specific creature within 120 feet of you as a standard action, you can determine whether it has any spellcasting or spell-like abilities, whether these are arcane or divine (spell-like abilities register as arcane), and the strength of the most powerful spell or spell-like ability the creature currently has available for use. As with [_detect magic_](/spells/detect-magic), you can use this spell to identify the properties of magic items, but not artifacts. _Arcane sight_ can be made permanent with a [_permanency_](/spells/permanency) spell.
