Arcane Archer Adept

You have training in Arcane Archery that allows you to infuse some of your arrows with magic. You gain the following benefit:

• You learn one arcane shot of your choice from among those available to the Arcane Archer archetype in the fighter class. If an arcane shot you use requires your target to make a saving throw to resist the shot's effects, the saving throw DC equals 8 + your proficiency bonus + your Intelligence modifier. You may choose to use your Arcane Shot option when you hit with an attack from a longbow or shortbow, unless the option does not require an attack roll in which case you must declare the shot before you make the attack. You regain your use of this ability on a Short or Long  Rest
