That would be quite a feat! I tried again and did manage to do it at level 4, but I think I could have avoided even more XP. I really doubt it can be done at level 1, though. There is a lot of exploration XP and using the bloodstones/star stones also grants XP. But maybe you can prove me wrong.
At the same time, it doesn't help much if you don't have the $$$ to buy the books every level, and they are expensive.
Whether I am successful or not, I will put my walkthrough here.
Even if I'm not successful, I am pretty sure that I can open the room with that one of the protagonists Lev 1 and the other Lev 2.
But game totally become another game.... to challege the game designer's plot by avoiding as much xp as possible.
