Maybe the accuracy calculation only kicks in when the monster's level is higher than yours, meaning you can hit everything below your level regardless of accuracy. Iono, just speculation.

No, I don't think so. Wild Hunters, whose main stat is DEX, still miss on monsters even one level higher than them. If you're a lower level than a monster, you will always have a set chance of missing.
