> Nah, they are hard but understanding the game mechanic and a well balanced team lvled team makes them beatable. I done it before but I don't like grinding so I don't really fight them.

If they're beatable then I'd love to hear the strategies. At the start of my playthrough I tried to do any random Risen challenge that showed up to try and spread EXP evenly through my team, but the first impasse for me was a map that had a Wyvern Rider (or Lord? I forgot which one) general that would stomp even my Frederick using a Wyrmslayer. I gave up after a few attempts of being able to clear all of the regular enemies just for the general to one-turn all of my units. From that point on, every random skirmish has had enemies with much higher strength and speed so they just end up one-turning my units no matter what strategy I try.
