[Nezha] has several synergies in his base kit that can be used against almost every type of mission. We subsume a CC ability that groups enemies together to make better use of a charged [Reaping Chakram].
Ensnare is chosen because it pulls large groups of enemies into a small area which can then be combined with Divine Spears and [Reaping Chakram] to nuke the entire group. Larva works better for charged Blazing Chakram throws as Divine Spears can't grab enemies under its effects.
Warding Halo or Fire Walker can be replaced depending on whether you're using a passive or mobile build.
[Enemy Radar] mods help you and your team to find enemies. The nature of this build sometimes forces you to track down stragglers.
Controlled Slide is only used because this is a learner build for most players and his passive is extremely off-putting. Replace it with a regular [Power Drift] or any other exilus mod that fits into the polarity plan.
[Transient Fortitude] can be swapped out with [Blind Rage] if you're confident with your energy economy.
Range can be lowered a bit depending on the tileset. [Rolling Guard] or [Vitality] can be substituted in for those mods.
Arcane Velocity is primarily run due to the [Kuva Nukor] synergy. It can be replaced with any other arcane to suit your playstyle.
