Nex

The easiest way to fight Nex is to camp Ranged with the best crossbow you can get your hands on, as the gear is a lot cheaper and still almost as effective when compared to Hybrid setups utilizing Melee gear. Keep in mind that while Armadyl IS technically better than Karil's or Ancient d'hide, it's far less cost effective and you're better off saving to upgrade to each Masori piece individually and skipping the Armadyl armour altogether. The most important stats are your Ranged attack, Ranged strength, Magic defence, Crush defence, and Prayer bonus.
