Arcane Shot

At 3rd level, you learn to unleash special magical effects with some of your shots. When you finish a long rest, you can imbue two touched pieces of ammunition with magic, turning each one into a different Arcane Shot option of your choice. This number increases by 1 when you reach 7th, 10th, 15th, and 18th level in this class.

Once per turn when making an attack with a ranged weapon, you can use one of your Arcane Shots instead of a normal piece of ammunition, spending its magic to cause the effects listed in its description. If the Arcane Shot required an attack roll and it missed, you can transfer the magic to a new piece of ammunition as an action. When you finish a short rest, you can refresh a number of spent Arcane Shots equal to your chosen attribute bonus (minimum of 1).

Curving Shot

At 7th level, you infuse your ammunition with magic which can direct an errant shot towards a new target. Your ranged weapon attacks are always magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage, and when you miss with a ranged weapon attack, you can use a bonus action to reroll the attack roll against a different target within 60 feet of the original target.

Additionally, any missed Arcane Shots magically return to your quiver at the end of your next turn.

Improved Arcane Shot

At 10th level, your Arcane Shots options improve, as listed in each entry right here: Piercing & Seeking see end of this page; the rest, the damage increases by 1d6.

Wildcard Shot

At 15th level, you gain a special Arcane Shot which does not count against your maximum. When used, this Wildcard Shot has the effect of any of your other prepared Arcane Shots, chosen at the time you use it. Once spent, the Wildcard Shot magically restores itself after ten minutes.

Greater Arcane Shot

At 18th level, your Arcane Shot options improve again.
