I was fighting a master vampire and I didn't see any messages saying I contracted any diseases but I can't figure out how to check if I have. How do I do this?

Lick your hand and then smell it.

Go to your magic menu and check active effects.

I believe you go to magic, and check active effects, or what ever it's called, it's like the bottom most option.

Go into your Magic menu and at the bottom is Active Effects or something, that shows all your buffs/debuffs.

YAY!!! Thank you!

EDIT~~~~~

Thank you two as well!
