Ring of Weapon Charging

The ring 'charges' any non-magical weapon the character has in his hand with combat spells, turning it into a +1 (both to hit and damage) weapon for 10 rounds.  The weapon will glow with a dim reddish light.  After the magic wears off, the weapon returns to normal.  Usable 3 times per day. Charging a weapon via the ring is done simply by the wearer willing it and is considered a bonus action.
