Roaming as in nekkers, drowners and other little punks? They cap out at 19 as far as I've seen, and even those are rare. 8-15 is the common range.So what are the highest level roaming monsters you find? I'm in Velen / Novigrad and outside of only one cave, I've never seen above 16-18.
Does shit get really hard in Skellige? I like the feeling of having to flee for my life that I mentioned above.
Skellige has level 21 cylopses walking around here and there. Specific places, like nests or points of interest and so on, can have enemies all the way up to level 50 or so. They vary wildly and you can find a level 35 forktail just a short walk away from a level 7 wyvern. There's a crazy-ass griffin in Skellige that one-shots me through Quen even though I'm level 30.
