As you complete the spell, runes bloom in the air before you, a deadly barrier made visible.

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 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. If you focus on a particular aura (as a major action, or more for more complex magic), you may use the Spellcraft skill to try to determine the rough function of an aura (make one check per aura, DC 15 + spell tier). If you attempt to analyze an overwhelming aura, a Spell save may be called for to avoid stunning or worse.

If you concentrate on a specific creature within 120 feet of you as a major action, you can determine whether it has any spellcasting or spell-like abilities, and the strength of the most powerful spell or spell-like ability the creature currently has available for use.
