Nex, one of Zaros’s most powerful weapons of war, has reawakened after unknown years of enchanted sleep and imprisonment. Only the strongest will survive the encounter if they dare enter the ancient prison that lies behind the fabled frozen door.
To open the frozen door, you will first need to obtain a frozen key. This key has been divided into four parts, with the four existing factions each guarding one of those parts. Given that they have sensed Nex’s reawakening, you might find them more willing to drop their part of the key, and with it pass to you the responsibility of keeping Nex contained.
Only the most dedicated followers of Armadyl, Bandos, Saradomin and Zamorak were entrusted with a key part, so you will need to access each faction’s stronghold (not the boss room) and defeat them for the drop. As such, the requirements to get all four key parts are 70 Agility, Constitution, Strength and Ranged. Once reformed, the frozen key has five charges before stuffing it in the frozen door will destroy it, but this can be prevented if you have a repair stand in your player-owned house and at least 50,000 spare coins.
Some things to keep in mind for those who dare to brave the ancient prison:
1.The last army of Zaros has been frozen for longer than anything else in the dungeon. As such, you’ll find them even more aggressive than the other creatures here (and some have special abilities). Have a plan of attack ready, or even getting into the boss room will be harder than you think.
2.If you are strong enough to get your Zaros kill count up to 40, you’ll be able to proceed to the next chamber where the prison’s warden resides. This is a good and safe opportunity to fully prepare yourself (and make a new friend) before heading on to fight Nex.
3.Nex is extremely dangerous! She can navigate the map with great intelligence, and uses a very powerful arsenal of attacks and special abilities – you will need help. Please do not take this warning lightly and only go if you are prepared to suffer death.
4.The only way to exit Nex’s chamber is to teleport out.or to die! Memento mori.
