Keen Weapon

Level: 1
Range: 30 ft.
Target: One weapon
Duration: 5 rounds
Your words make a weapon shine with silver potency, capable of dealing more punishing blows than normal.
You can augment the critical threat range of a weapon by speaking its truename. This utterance functions as a keen edge spell (PH 246) with a caster level equal to your truenamer level, except as noted here. In addition, you can change the threat range of any weapon you name, not just piercing and slashing weapons. The weapon you deliver this utterance upon pulses with a silvery sheen throughout the utterance’s duration.
