For instance: a spell says "Int vs AC" Do you roll raw int + d20 vs AC?
Do you roll Int bonus + d20 vs AC?
Do you roll int bonus+weapon accuracy +d20 vs AC? (This is a question about swordmage, so I have a melee weapon AND cast spells)
Please help. We've been confused on this and it seems like it'd be pretty crazy to just take int bonus +d20
