Divine is wisdom based,arcane is intel/charisma based.
so bard/wizard/sorceror are your 3 choices for arcane.
Wizard is intel,bard/sorc is charisma based.
Your best bet is to go bard <1?>/cleric/pale master,especially since clerics get a turn undead bonus from charisma.
Sorceror would work also,if you want more magic and weaker combat skills.
