Thanks for reporting!
- 1: The Oblivion potion thing is an oversight, it was introduced far before the tome skills. I will take a look at fixing it
- 1a: That is a bug, either the enchanted weapon bug, or something else. It should be a magic weapon (I fixed something like that with the update on the 5th of December). Will take a look
- 2: There are many balance changes coming, and still more are in development. I hacked on-screen combat in one version before this one, and it still needs a lot of love
- 3: More armour is coming eventually, will take a look at the balancing
- 4: Fixing the chest drops would be possible, I will put it on the list of suggestions for future content
