How can gnomes level 20 with Guild of Merchants, but without a cart, take on 35 green lizards and then defeat 40 gold golems? It seems a bit strange to me.
If we don't take critical morale into account, then reaching the maximum level with Guild of Merchants is quite easy.
I won't argue, I just don't understand. 12 shots, maximum level, 3000 HP – so the lizards should take 250 HP per shot.
P.S. You're not alone in your misunderstanding :)
