so i was roaming around xentales and i found this interesting thingy where xenstats got calculated, by Ej's norms i guess, so you might want to look into it to check if you can tweak spells etc the same way?
http://calc.xentales.com/
Noticed by playing with this calculator:
-Level increases health differently by class cause of balance, but damage doesnt increase unless statwize.
9% base each level for fighters/warriors: because of lacking magic abilites
6% for rangers/hunters: because of survivability(hide skill)
6% for paladins: maybe cause of their magic abilities
9% for barbarians: Because of their lack of magic abilities
4% for warlock: more than wizard cause of certain survivability spells
3% for wizard: more damage
3% for cleric: more survivability heals armors.
-There are confirmed bonus stats that ej added, but i supouse they used to be secret, aim was to let players make a special character build then increase after the bonus didnt work good enough anymore.
-strength only increases health every 6 points.
-You only gain spells every second level.
-what certain stats mean for certain classes.
What i found out, hope this somehow helps devs.
