Interesting! I was hoping that the exposure to magic would make the players interact with various cultures. For example, a certain species/race is very good at a certain type of manipulating the magic, so they would be required to travel there in order to learn more.
I was also considering spirit magic! Using up your own spirit power would make an interesting magic limitation. Thanks for the suggestions! :)
OH! I totally forgot I wanted to play that mod. To be honest, I looked hard into Skyrim lore in order to figure out a way to implement some of its magic into this RPG. However, I’m at a loss regarding all the deities that would interfere with the world, or different planes of existence (from which mana comes).
The going mad part would fit though, as I was hoping to make it dark fantasy :D Taking owl’s response from above, it could be a result of using up your soul haha
