Yes, Master Herbalistis that skill

I don't know HOw you play the game before you have your Battle Tower, but I think it is always possible to find a solution to go futher with the game.
I personally prefer to combine warrior with mage and ranger... So I use a bow, a sword AN magic too! I think a pure warrior is more difficult to play, certain if you're not so skilled with games AND that's NO shame! Everybody once begin one day his/her first game

!
I think you can't do realy BAB things, make bad choices! It's most of the time a personal choice to play a RPG on your own way. BUT, everybody can learn from each other, for sure

How I play my second playround:
I play again still on "easy difficulty". I play now without buying anything from a trader.... All I can find from loot I search out the best equipment etc... and all the rest I sell! So my amount of gold is great now on level 16

... I think I have 37 000 goldcoints now.
I don't spend skillpoints in Master Herbalist.
