Righteous Might

Your height immediately doubles, and your weight increases by a factor of eight. This increase changes your size category to the next larger one. You gain a +4 size bonus to Strength and Constitution and take a –2 penalty to your Dexterity. You gain a +2 enhancement bonus to your natural armor. You gain DR 5/evil (if you are good or neutral) or DR 5/good (if you are evil). At 15th level, this damage reduction becomes 10/evil or 10/good (the maximum). Your size modifier for AC and attacks changes as appropriate to your new size category. This spell doesn't change your speed. Determine space and reach as appropriate to your new size. All equipment you wear or carry is similarly enlarged by the spell. Weapons deal more damage. Magical effects that increase size do not stack.
