Wand Master (5e Feat)

Through extensive research and long hours of practice you have mastered the use of wands, gaining the following benefits:

You gain a +1 bonus to attack rolls and to saving throw DCs with spells cast from magic wands.
Magic wands you are attuned to have 1 extra charge.
You can hold a wand in each hand. When you use an action to expend a charge with one wand, you can use your bonus action to expend a charge with the other wand. Doing so expends an additional charge from both wands.
