I really like the premise and the quantum ogre joke therein! Portal dungeon is a great idea!
I did have to go back and double check the system a few times early on because there are instances where DEX and AGI are interchanged.
Additionally, I was left a little confused about what happened with the spell book / ring combo miscast until I read through the whole thing and was able to piece it together with the locations Y2, H3, H3. This could be a personal issue!
Overall great work! I liked the map and notes on it!
