Colourful Wings

On your command, you enhance the arrows and bullets of your allies, making them appear as colourful missiles with tiny wings. They seem to hit their targets more likely, even when they're hiding.

All allied nonmagical projectiles within range, are affected by your spell. You don't have to see them, the ally that shot it or the target. 

Any ranged attack roll made with such an enhanced projectile adds +2 on the attack roll and is unaffected by half or full cover. On a hit, the projectiles deal an extra D6 radiant damage.

At Higher Levels. If you cast this spell using a spell slot of 5th or higher, the damage increases by  +1D6 per spell level above 5th.
