some comments to the OP:
- I enjoyed playing NWN2 and PoE
- Josh Sawyer is not with Larian
- You have posted mystic lich spells. Those cannot be found anywhere in the official rules.
- At the moment we only have lv4 chars with lv2 spells. Nobody knows how higher level stuff is implemented.
- The game is based on DnD 5E. I agree that some of the DOS stuff is bad, but if you do not like 5E then you will still hate the game even if they implement the rules properly.
