Wondrous Item, uncommon (requires attunement)
You attach a scope to your long firearm and enchant the lenses with Divination magic. The scope has 4 Charges. As a bonus action you can use 1 charge to cast hunter's mark. As an action you can use 2 charges to cast see invisibility or 3 charges to cast clairvoyance. You also gain the effects of the Sharpshooter feat.
- Attacking at long range doesn't impose disadvantage on your ranged weapon attack rolls.
- Your ranged weapons ignore half cover and three-quarters cover.
- Before you make a ranged attack with a ranged weapon with which you are proficient, you can choose to take a -5 penalty to the attack roll. If you do so and the attack hits, it deals +10 damage.
The scope regains all charges after a long rest.
