Epoch has abnormal stats in my game too. (Maximum might and attack - the other stats are okay)
It happened previously or at the checkpoint before you meet up with Slades again.
I don't know how it changed - maybe through a new item or anything?

But overall I like your game - it's very interesting and nice to play.
And your mapping is better the longer you play it. ;P

And yes, the inventory is really too big.
I can't even sell the rusty sword or other old items.
Maybe you could fix that or add an option to remove items?

Anyway, I will play more and perhaps write again something.
