I am making a vampire advancement system that uses how long you have been a vampire as variable 1, and how many times you have fed as variable 2. this will be used to create a two word vampire rank with the first word their age and the second word their feed count. So they could be a fledgling bloodsvcker or fledgling leech, or fledgling nightstalker if they are age 1 and feed count 1 2 or 3, etc. If they are age 2, then they would be a young bloodscuker, leech or nightstalker. At age 3 they could be a mature bloodsvcker, mature leech, or mature nightstalker, etc.
