And if you don't, the game will be extremely hard and will require an excessive optimization of every characters.
This is something i find indeed curious ...
So many people around here is complaining about game being "extremely hard" in such cases ... what does it even mean?
Since i concider myself being a noob ... i have almost none experience with DnD, even less with pure DnD, and even tho i do play many RPG there isnt many like BG-3 out there (at least not in my opinion) ...
Yet, in my few first playthrough i runned openly into every fight that was there and even tho some (namely Gith, Minotaurs and Bulette) was toughter and required me to think a little in advance ... i would never say "extremely hard". O_o
