Okay, here are the rules (for all spell casters) :
Cleric/Druid/Rangers/Paladin need wisdom for their
spell casting effectiveness.
Sorcerer/Bard need charisma.
Wizard (specialist or not) needs intelligence.
Your attribute (wis or cha or int) limits the level
of the spells you could prepare/learn. Your attribute
must equal (at least) 10+spell level.
Then DC for the saving agains yours spell is :
10 + spell level + your attribute bonus + feat
"spell focus [school of magic]" (grant a +2)
Your roll to bypass magic resistance is :
d20 + caster level + feat "spell penetration" (grant a +2)
Have fun.
