Increasing attribute just for spellcasting

[frumple]

Could use some ideas on this one.

I have an ability that adds to a character's attribute for the purposes of spellcasting only.

In other words, for a cleric it would add to the Wisdom attribute for the purposes of determining spells allowed, bonus spells, spell DCs etc.

Ideas on how to implement?

Currently my only thought would be to adjust the "values" on the Class Only. IN example on the cHelpClr Thing is a field called "cSplAttBon" where you maybe able to increase to have it affect stuff.

Worse case you have to give "bonus" spells by affecting the cCastTot matrix. Maybe you get really lucky and by affecting cSplAttBon it affects everything about the class.

I have not tested any of the above ideas. But that is how I would approach the issue.

Yeah, that is what I thought. I was hoping there was an easier way. :/

Figured it out (I think).

Here is the code. abValue is the amount of increase

Timing: Post-attributes/500

perform hero.child[cHelpClr].setfocus

focus.field[cSplAttVal].value += field[abValue].value

var atrBon as number
atrBon = focus.field[cSplAttVal].value - 10
if (atrBon >= 0) then
  focus.field[cSplAttBon].value = round(atrBon/2,0,-1)
else
  focus.field[cSplAttBon].value = round(atrBon/2,0,1)
endif

if (focus.field[cSplAttBon].value > 0) then
  focus.field[cSplMaxAtt].value += field[abValue].value
endif

~ set bonus spells
var cnt as number
cnt = 1
while (cnt <= focus.field[cMaxSpLev].value)
  var bon as number
  bon = focus.field[cSplAttBon].value - cnt - 1
  bon = round(bon/4,0,1)
  bon = maximum(bon,0)
  focus.field[cMemMax].arrayvalue[cnt] += bon
  cnt += 1
loop
