Having trouble clarifying the Polymorph Self spell. Would I, as an 8th level Wizard (3rd /3.5 Edition) be able to Polymorph myself into a Frost Giant (Large)? What differences should I have (HD, HP, AC, etc.) My DM is OK with it, but is wondering if I need to be the corresponding level (14) to turn myslef into a creature with that many Hit Dice (14). Is this true?
