Just in case Horngeek (Evalie?) doesn't get a chance to post, I was going to enchant Evalie's bow with my Augment Energy class benefit:
You infuse a weapon or an implement with a reservoir of energy that lasts until the end of your next extended rest or until it is expended. The wielder of the implement or the weapon can use a free action after making an attack roll to expend the reservoir of energy to gain a +2 bonus to that attack roll. An implement or a weapon can be augmented only once per day in this way.
At a new milestone, I gain the ability to re-use this on a different ally's weapon, or I can choose to recharge a daily item's use via Impart Energy:
You recharge the daily power of a magic item. An item can be recharged only once per day in this way.
Think I'll edit the use of Augment Energy into my last post in case Horngeek doesn't post.
