So, to be hones, It's not like i have survived for weeks or so but I've had my share of levelled skills. mostly weapons and cooking/crafting skills but I never managed to level one of the agility skills. what would one have to do to level the agility skills? (Sprinting, Nimble, Lightfooted, Sneaking) and for how long would I need to do that? PLUS: Is there a way to increase levelling for other skills than cooking, crafting and farming?
