Nex is one of the most powerful generals of Zaros.A suitable weapon sometimes will be the key to win. Therefore, as for defeating Nex, Dual Wielding vs Chaotic Staff, which one will be better with cheapest rs 07 gold?
Chaotic staff
A chaotic staff is a two-handed magic weapon. You need a Magic level of 80 and a Dungeoneering level of 80 to wield. Once you own it, it can be used approximately 10 hours of combat. Once these charges have been used up, you must be recharged before it may be used again; it has a 20% charge on purchase. 
Using a Chaotic staff, a player using Magic spells can easily reach close to their Max Hit. This is due to the 20% damage bonus that comes along with the staff.

Dual Wielding VS Chaotic Staff
1. The dual wield setup is superior because Concentrated blast is an awesome ability.
2. Dual wield is better if you plan to use debuffs, otherwise the Chaotic Staff is better being able to increase the accuracy of your next hit using Sonic Blast.
3. Dual wielding is always better, because you can camp shield.
