Arcane Meditation

While the spell is being cast, the caster enters a state of meditation where he does not perceive any stimulus external except pain, cannot move or perform actions (except using an action to stop meditation) e he must maintain concentration (if concentration is interrupted within the first 42 seconds the slot does not come lost). At the end of the meditation the caster awakens and for 24 hours has the same effects as Arcane Sight (which is another spell of my creation :D) with a range of 1km; the aura around a person now detects all available slots of a creature (even if it has already been used) and the aura around an object now always reveals the spell applied to the object and allows the caster to learn it with an Arcana roll with DC equal to 20+ the spell's level.
