Mods I will get day one if possible
Faster dice roll
Armor dyes
More head/hair presets (only modders have the skill to make nice hair and eyebrows in any rpg, apparently)
Party of six (or ability to keep all characters at a camp in later acts if they go all DoS with it)
Magic mirror (to change appearance on the fly)
Increased zaniness and random effects for Wild Magic
And most importantly —- NO MORE DIRTY FACES (because I like to think my party are smart enough to wash their damned faces)
