Hey,
just found some interesting feature.
I started new game as a Skelly, and in the very first room there was Locker. It was empty since I had 4 spellbooks in it and played as Wizard last game (killed Satan no problems whatsoever … Wizard is too easy).
So I dumped into it one magic potion, sleepy arrows and rotten meat, and started new game.
In that new game, I found locker AGAIN on the first level, not in the first room, but never the less at the very beggining of the game. Dumped all my stuff in it as well, and started third game.
You can see where this is going … maybe disable Locker possibility on first level?
