I = 1
II = 2
III = 3
IV = 4
V = 5
VI = 6
VII = 7
VIII = 8
IX = 9
X = 10
As far as I know there are only 10 levels.
It is pretty vague why numbers such as 9 show up as IX, but if you read a bit about what it means you would understand with no problem at all.
Hope this helps, those who don't know.


What levels do to creatures.
Most people know this, but for those who don't, a creature's level as far as I know only modifies their health variable and LP gain. Each creature has it's own health level. Health levels for creatures on this game are only determined by "animallevel*X" and X is the variable. An example of this is the godforsaken bear, their variable is 80. So if you fight a level X bear, you are fighting a bear that has a health level of 10*80. Levels also determine LP gain for defeating that creature, in the bear's case they have "bearlevel*200" for the newbies that is a lot, but for somebody even capable of getting into combat and not getting slaughtered the first attack that isn't much. Another example of this is the fox. A fox has a health value of "foxlevel*20" and they have an LP gain of "foxlevel*40".That is what the point of levels are on this game.
