The mage gains the Mage Sight[1]. This spell is especially good for reading resonance that is ponderous (“thick”, “sluggish” or “dense” as some have called it).
See Resonance[2], for rules on scrutinizing magic with this spell. The mage gains a +1 dice bonus when studying dense/very dense resonance, but suffers a –1 dice bonus when reading refined/ very refined resonance.
