Thanks for playing! I was hoping to capture those old school dungeon-crawling experience. I was even thinking of implementing an old school descending AC styled system but I felt like that would be too much of a hassle to understand for most players.
And yeah, MND right now is mostly a dump stat. I had originally planned on making much more advanced enemy AI and have them able to use hexes against you, and you would need MND for saving throws against them. But right now, MND really only mainly affects how well you can see if there is an enemy in the three paths you can take and a small part of increasing your sanity and memory.
INT is really good if paired with a secondary stat like DEX imo. It makes enemy with a high Damage Resist much more easier.
