so. i want to start a wizard for the trap monkey with high int. and the ability too cast offensive spells. also, would having 6-8 STR make a caster weak at all? does STR count for your magic damage?

would i be able to max out DEX/INT/CON and have a good wizard/ranger maybe arcane archer and wizard. would having 6-8 STR lower my damage when attacking with a bow?

and last but not least. would i be able to make a kensai ranged build and use magic arrows with that for extra feats?
