NEZHA GUIDE AND BUDGET/ALTERNATIVE VERSION: HERE

[Combat Discipline] is kept unranked as we only wanna get that 1hp of damage to trigger Arcane Avenger which will trigger Arcane Acceleration or for that matter, any other Arcane that might need an "On Critical Hit" condition, flex arcane for your load out.

If you are ok with taking -10HP/Kill Rank it and forma the polarity for extra capacity, this could save you 1 Umbra Forma.
Or u can just do it without umbra mods. This will lock [Transient Fortitude] in place and lower your EHP, but that's it. Much more affordable.

We only need 200 STR to take full advantage of our 4, anything extra is for our 2 and 3. So [Transient Fortitude] = Flex but Augur Secret is mandatory on [Nezha], look at my previous guide to know why

Thank you @Kevidiffel for the suggestion.
[Stretch] over [Transient Fortitude], for flex as [Stretch] feels better.

It's possible to increase the range further, by dropping Umbra Fiber and Augur Secret.
Swap in Transient Fortitude and Augur Reach.
The trade-off is lower EHP (Bye-bye 1M), no flex slot -> negative duration locked in, that said:

Negative duration doesn't affect us much if at all.

1 is spamable and low cost
2 10 second window of vulnerability is more than enough TTK
3 Dosen't use duration.
4 Dosent use duration.

Aux is flex
Speed Drift: I just like to have some cast speed and sprint, great QoL maybe u want more STR? up to you.

EHP:
10816 "base" / (0.1 Halo * 0.1 [Adaptation]) = 1.081.600

We have between 108K(with only Halo on) and 1M depending on [Adaptation].

Why Tharros Strike?
For armour stripping, we could double our damage output with Roar or other skills, but the armour will always be a factor in how much damage we are doing.
Remove armour from the equation and well, you open up your own Meta.

Why 2 damaging Arcanes?
Cuz Nezha can
Your energy is no issue, we make energy with our 2 and we have low-cost skills, all but our 3 that we don't/can't spam.
Your defences are no issue, behind 3 different DRs, a relatively huge HP pool, a small SG and HP Orbs everywhere.
