@ Krschkr: You mentionned that summoning had less of an impact the further you got in the game, did you stayed at 10 summoning or pushed it at 20? That could've changed your view on it.
That being said, I think I'll do as you did: diversify myself to get more skills and better weapon damage. I'll try a ranged build, so hunstman, warfare, ranged and necromancy seams the way to go. Would it be worth it then to put one point in geo and hydro for the armor boosts and other utility spells?
Thanks for your reply btw.
