I have no DnD experience, but I do have DOS2 experience, so as long as I manage to make things go "bang" and send someone flying out of a window, it is fine by me. Said so, after +100h in, I already know how most of the stuff works, even if I don't really try to use it. After all, there's nothing that can't be solved by using three Call Lightning spells of my Storm Sorcerer on the same turn.

But yeah, for someone who doesn't understand shit but also tries to understand it, it must be overwhelming.
