For anyone interested in how some of the stats are calculated and more in the story, here's the equations that I worked up.
***Decimal Values Are Always Rounded Up***
HP = 1/2Rank(Resistance + Vitality)
SP = 1/2Rank*Vitality
MP = Rank*Intelligence
(Stronger/Equal Level Creatures)
EXP Gained = 10 + 10(Total-Level-Difference^2) + (100 * Total-Rank-Difference * Total-Level-Difference)
Rank 1, Level 1 --> Rank 2, Level 1
= Total-Rank-Difference of 1
= Total-Level-Difference of 10
(Weaker Creatures)
EXP for defeating same Rank & Level is 10 EXP
Each Level lower decreases EXP gained by 20%
Defeating lower Ranked creatures gives 0 EXP
(Stronger Than Nox) Raise Undead Cost = 5*(1+Total-Rank-Difference)*1.5^(Total-Level-Difference)+(5*Target Rank-5)
(Weaker Than Nox) Raise Undead Cost = (Target Rank*5)/(1.2^Total-Level-Difference)/(1.3^Total-Rank-Difference)
Inevitably there will be more calculations I'll have to do for new abilities and whatnot but for now this is it.
Also, I apologise if my maths sucks, I'm trying my best here :)
