Not to be confused with ordinary merfolk, merrows are larger-than-humanoid monstrosities, the descendents of merfolk warped by demonic influence in the ancient past. Since they’ve bred and survived since then, we can consider them evolved creatures despite their supernatural origin.
Merrows are water-dwelling creatures, drawn to coastal areas with a lot of marine traffic, where they prey on anyone and anything weaker than themselves. While they can breathe both air and water, they flounder about at a pitiable 10 feet per turn on land, but in water, they swim at a brisk 40.

They’re not that bright, but they can tell when they’re getting beaten. They also have darkvision, so the hours from twilight to dawn are particularly dangerous times to be messing about in boats where merrows roam.
