[Firewalker] should always be cast. Great for keeping enemy's stunned in flames. Also great to cast while sliding or in the air so you don't ruin any momentum. The augment mod for this ability ruins momentum so i see it as unusable.

Chakram should be cast on enemy's you need more damage on. Also good to cast when you need energy and health orbs. Casting the ability again to teleport is good to use when enemies are grouped up in your [Firewalker] flames. Also can be useful to teleport to extraction when your momentum is ruined.

Halo should always be casted as well. Best to cast when under fire. Halo should make you stagger resistant. So [Nezha] can make self staggering weapons useful.

Ultimate is good when you need everyone to stop. Also easy to hit many enemies with your chakram when they're impaled.

Your movement should be sprinting then sliding. Learn to slide up to corners then you can bullet jump in the path you need to turn. This allows for fast 90° turns.

The aura mod is to purposely lose health to be able to pickup health orbs which maximizes use of [Equilibrium].

This build is focused on the ability [Firewalker] and your halo because these abilities are the best in the kit. The chakram is amazing for increasing dps and greater chance for energy and heath orbs. These abilities are cheap and you should always be good on energy. [Nezha] is my most used frame and looking forward to using this prime. Have fun!
