Since you're new with the game there's an extra tidbit that I'm sure you'll find very helpful (if you haven't learned about it already)
You can refund your attributes, taking them off skills you've added to already and putting them back into your storage. This gives you unlimited versatility and experimentation but you can't do this too often in a short time span. Everytime you do it you lose a "refund point" of which you have 24 total. That's plenty of points needed to fully rearrange your build, but not quite enough to change back afterwards. However, you gain 1 refund point for every 250 xp you get so worst case scenario is you have to live with the current build for a few hours or a few gaming sessions before you can change back.
Apologies if you already knew about this (I don't know what's in the manual), but as you said you were new and nobody else mentioned it I thought it was worth bringing up
