I think it works because you keep hitting the swordsman so they have less time to hit you back. You need to keep overkill mode for at least 40 seconds lol.
WOW, I started a new round with my dungeon and the funniest thing happen. A rogue actually went from lvl 1 to 15 in one run. It made it all the way to the dragon where I had to stop it since it had no items = dead.
Soloing the dungeon is easy, just make a big space beside the dragon so you can heal and stall for time so your other heroes can come. When i played, my paladin was my highest dmg, which is kinda dumb (80dmg)
Dam i didnt think that you only attack the dragon once per square, thanks to that it took so long for my heroes to nail it. (my first hero could have soloed it its lvl 16, it took so long even when a lvl 15 and 14 came :( )
Does anyone notice the black blade trio was wayyy harder than the boss. It was due to their 70 regen crap, high armor. I had to literally break all of their armor so my damage could destroy their hp. The armor peircing skill was terrible with its bad acuracy.
