Just tried out all of the other classes and if you try the game you should start out with the warrior...compared to the other classes he is a good hero to get into the game.

Some of the others seem really weak in the beginning because they have way less hp/weaker starting dmg.

The necromancer though is a fun class..starts as a 1shot for everything (with only 5hp) but has an insane critrate and will get +2permanent hp for every healitem picked up(normally for all other classes just a 5hp heal)
