Charged Weapon

At 1st level, as a bonus action you can charge your weapon with the power of the tempest. When you activate this feature, you can charge your bow or crossbow before firing it. Once per turn, you can deal an extra 1d4 damage to one creature you hit with an attack from your bow or crossbow. The damage is either lightning or thunder (choose one). The damage increases to 1d6 at 3rd level, 2d6 at 5th level, 2d8 at 9th level, 2d10 at 13th level, and 2d12 at 17th level. This effect lasts for 1 minute or until you dismiss it.

You can use this feature a number of times equal to your wisdom modifier, regaining your uses after finishing a long rest.
