The Nex boss is available in 3 wilderness locations, one in multi combat and another one single combat and the last one in the Royal Donator Zone. All of them have the same drop table, and same attacks (final nex phase).
Keep in mind that the Nex boss is extremely difficult to challenge and it's levels raise based on the total number of attackers.
There are semi-direct teleports to the boss via the Teleport Wizard. (::nexmulti, ::nex and ::royal)
Nex will only use her melee and non-attuned magic attacks.
She has very high hitpoints and deals relatively high damage even through protection prayers
In addition, she will use several Ruinous Powers, which are Zarosian prayers, in this fight:
Soul Split - An overhead prayer in which Nex will heal a small percentage of her health for every successful hit she inflicts.
Deflect Melee - An overhead prayer in which Nex will activate a variant of protect from melee that deflects the damage the player would have dealt to her with melee attacks.
Wrath - An overhead prayer in which Nex shouts Taste my wrath! This is a stronger version of Retribution, and deals up to 50 damage to players within a 5x5 radius of Nex upon her death. Players have three seconds after her death to run away from her Wrath attack.

The easiest way to fight Nex is to camp Ranged with the best crossbow you can get your hands on. 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 void and skipping the Armadyl armour altogether. The most important stats are your Ranged attack, Ranged strength, Magic defence, Crush defence, and Prayer bonus.
Warning: This boss is located deep within the Wilderness, beware of player-killers! Do not bring items you are not willing to lose.
