Okay, took me a bit to figure this out. Was testing out with my mate f2p. There's no special attacks, instead there's where the spell book Is there's what's called abilities. There's different ones for Mage range etc and basic abilities. Use the basic abilties to build up your adrenaline bar aswell as normal attack
