General purpose [Nezha] Build utilising Umbral mods, mostly for arbitrations and the like.

[Nezha]'s abilities last for a decent while even without much duration, so duration mods aren't that valuable. Range, however, makes Divine Spears far better as soft CC and combos even better with Blazing Chakram as there are more targets for it to hit... thus activating [Reaping Chakram]'s bonus. Thus meaning more damage. Thus meaning more health orbs. [Cunning Drift] is also really good for [Nezha], as every single one of its stats is amazing for [Nezha].

Transient Fortitude is more of a flex slot and can be replaced with any mod of your choice, same with Arcanes.

For a more support-oriented set up you could replace Reaping Chakram with Safeguard, however I dislike it as it means you will need to micro-manage teammates' own chakrams and that gets very annoying very quickly (bring a trinity or oberon or wisp if you want to support like that - they're better at it and don't need to target teammates directly!)

Always having Warding Halo up and during the period where it goes up, always try to soak up as much damage as possible for a chunky extra health bar.

[Adaptation] is used to make [Nezha] even more survivable and help you not die if it goes down during a moment of distraction. Furthermore, with the 90% damage reduction of the Halo already, this means that if you stacked [Adaptation] enough, you can get 99% Damage Resistance. Keep in mind it's not instant, but the Halo allows [Nezha] to soak up enough damage for this to happen.
