As a standard action, a spellblade magus can throw his athame up to 60 feet as a ranged attack (no range penalty). If the athame misses, it returns automatically to the magus' hand just before his next turn. If the athame hits, it deals damage and its duration ends; the magus can choose to spend up to 2 points from his arcane pool to increase the thrown athame's damage by +1d6 for each point spent.
