Discussion of level 1 monsters.

While updating the Cheat Sheet, I tested the units and found the following: Berserker is the strongest in attack, Zombie is the strongest in defense, Centaur is in between them, but the strongest (most durable) in prolonged combat, and can easily defeat any archer of its level. All other units are weaker. An Archer might be stronger only if the Centaur stands still and waits to be shot at. Therefore, the first choice is Centaur.
