ToME: the Tales of Maj'Eyal

Most of talents gains scales off linearly or it lowers with each level, i think its bad with each lvl of talent we should gain moar or just get better control how fast we gain it
So this is how i think it should look like using simple math


a = talentlvl / maxtalentlvl (or just talentlvl / 5)
b = 1 - a
value = b*b*start + a*b*2*mid + a*a*end

*NOTE* just chainging mid value

using this we can get simple curves like logarithmic :


linear:


or exponential:

Actually it is not linear for many things already.
Weapon talents, spells and such use a curve where the first points give more benefit than the last. This is wanted, to encourage spreading instead of overspecialization
