Units in Erfworld - Known information

[Freederick]

So we know warlords level up with XP from won battles.

If Stanley is only worrying about warlords, my guess is that basic units cannot level up, that fits quite well with the full life every day concept.

Or basic units level up some other way. My guess is that ordinary units level up by making a kill, but warlords only by winning a battle. That would mean that the dwagons did level up--a lot.
