Artillerist's Sight

You place a spell of heightened accuracy on a siege weapon, making it easier to use. For the duration, any creature aiming the siege weapon can see an arc describing where the projectile should land, gaining advantage on ranged attacks made with that weapon. In addition, the weapon deals extra damage of a type it would normally deal equal to three times the spell's level.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, it further compensates for effects like wind. Attacking at long range doesn't impose disadvantage on the siege weapon's attack rolls (meaning these rolls are also made with advantage).
