As he gains levels, a magus learns arcane secrets tailored to his specific way of blending martial puissance and magical skill. Unless specifically noted in a magus arcana’s description, a magus cannot select a particular magus arcana more than once. Magus arcana that affect spells can only be used to modify spells from the magus spell list unless otherwise noted.
