  • Engulf. The mill slug moves up to its speed, engulfing any target in that space. An engulfed target is made prone and restrained (escape DC 30) by the slug’s slime and takes 32 (2d20 + 10) bludgeoning damage at the start of its turn. If the slug moves off of the target it is no longer restrained.
  • Bite. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 36 (4d12 + 10) piercing damage.


Mill slugs have only the most instinctual of tactics. They will attack creatures with their bite if they perceive them, and otherwise will stop on top of their victims, waiting for their weight and their slime to smother them before eating their “catch”.


A gigantic slug, bigger than a barn, slowly oozes forward. It is 70 feet or more from eyestalk to tail-tip. Despite its soft body, its skin is tough and it leaves only a brown path of destruction in its wake as it consumes everything it can in its hunger.

Windmills. There’s quite a bit of debate about what exactly causes a mill slug to be attracted to windmills, but there’s no question they are. A mill slug will head straight for any operational windmill and attempt to smother it.

Mill slugs have even been known to lurk around the ruins of a windmill, seemingly waiting for it to begin moving again.

Edible. Mill slugs are edible but their flesh is inferior in both taste and texture to lesser gastropods and it is rare for anyone to hunt them for their meat. Living mill slugs avoid salt instinctively and adding to their meat causes it to shrivel and toughen.
