Skills in RuneScape have always tickled me because of the sheer variety on display, and this extends to Dragonwilds too. And of course you've got runecrafting, or agility. Simply running around on foot will get you passive XP for the skill now, so you'll be working while you're working! Your jump height is higher and you have more control in the air, and as you level up your agility skill, you'll use less stamina while sprinting, as well as have more carrying capacity. The agility update is out in RuneScape: Dragonwilds now.
