I believe that's if you have the "Sharpshooter" Feat.
Sharpshooter - PHB pg 170:
You have mastered ranged weapons and can make shots that others find impossible. You gain the following benefits:
- Attacking at long range doesn't impose disadvantage on your ranged weapon attack rolls.
- Your ranged weapon attacks ignore half cover and three-quarters cover.
- Before you make an attack with a ranged weapon that you are proficient with, you can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack's damage.
That's actually a potential synergy option when Rhydd and Mallory fight together. Depending on what Portent she has available at any given moment, she could potentially give Rhydd a really high attack roll to offset the -5 and ensure a good hit if a situation calls for it. Though given the +9 you're already rolling at (+10 after we get that magic bow for you), it's probably unnecessary. ^^;
