The bosses in that game are very tough. You almost beg for someone to nuke them, not like in FKG. But they last for 12 hours, so is kind of balanced.
Anyways, if someone is looking for active friends in X-Overd I have place for more [nutaku ID 4499760, Balkri].
(I will not rest in that game until at least unlocking all the combat maid scenes/storyes... so good so far)
