This build is suitable for any content you might need Nezha for. It's comfy and not over-the-top. This guide however focuses on [Nezha]'s Kuva Lich hunting potential (which is great IMO).

The synergy revolves around Blazing Chakram (2nd ability). This skill applies 100% (200% with this build) damage vulnerability debuff on enemies that got hit by the chakram, including Kuva Lich.

After you hit your Lich with your 2 - take your best DPS weapon and melt his face! Your lvl 5 Kuva Lich is gone within seconds!

My personal preference - [Kuva Nukor]. And that's when the Arcane Avenger comes in. With this arcane active your [Nukor]'s crits (with insane crit multiplier btw) are much more consistent.

Here is your max DPS rotation:
ARCANE AVENGER ACTIVE -- THROW YOUR CHAKRAM TO DEBUFF LICH -- SHOOT YOUR KUVA NUKOR OR ANY OTHER GOOD SINGLE-TARGET DPS WEAPON IN THE POOR BASTRAD'S FACE AND WATCH HIM MELT WITHIN SECONDS -- RINSE AND REPEAT IF HE IS SOMEHOW STILL ALIVE

Use [Hildryn]'s Pillage for even more survivability & debuffs.

Small bonus: [Nezha]'s 3rd ability provides knockback immunity which makes him a comfy explosive weapon user.
