First of all, sorry for broken english, I'll try to make as less gramatical errors as possible.
I'm working on a skill, but I'm not even sure I can manage to do it with skill formulas.
This spell, let's call it "Arcane Shock", deals damage depending on specific states ("Arcane Stain")...
I'd like my skill to display the average damage of it's formula in it's description window.
For exemple if my skill formula is :
( a.atk * 2 - b.def ) + 2
and my actor's atk is 10, I'd like the description window to say that it'd deal 21 damage average (based on an enemy with 1 def)...
