1Q:How do I get hair on my chest, arms etc?
A:You get more hairy the more you add in Thoughness
2Q:How do I get wider, more muscular?
A:By adding in Health you get wider, by adding in Physique you get more muscular. Still I also think Health gives you muscles to but they may not look as big or mighty as when you add in Physique.
3Q: Why do I get scars and how do I prevent from getting them?
A: You get scars if you get hit by critical strikes (the enemies weapons glow/flourish = critical hit) You may prevent this by adding points to your Thoughness attribute, you can also focus on using the Physical Shield spell and strenghten this spell for better protection and duration of the mana shield. Remember to buy will potions since you may want to use the mana shield alot for avoiding scars

6Q:How can I get tanned or paler, by being in the sun or moon for a period?
A: It was meant that you could bleach yourself in moonlight and tan yourself in sunlight in the first place during the development of Fable/Project Ego, but since the game got rushed it went a simpler way, now you get paler by doing evil deeds and tanned by doing good deeds.
