Probably the strongest setup for [Wukong], if you do not care about formas
Cloud walker to walk off any damage
Defy to increase [Adaptation] buff until it reaches 90% damage reduction
Roar for damage and to buff your twin

Main Idea: Buff primary weapon damage and abuse your twin
[Combat Discipline] rank 1 for least damage taken (you cannot rank 0 this unless u [Sacrifice] another mod), and it procs arcane avenger which brings up huge damage to your primary weapon, bubonico (with hunter munitions)
Secondary weapon - choose whichever you like. I like zakti / kuva nukor
Empty Melee weapon slot so you and your twin both goes pew pew pew
Primary weapon - [Bubonico], cus it does a lot of damage and you can use [Combat Discipline]+arcane avenger for enough crits, allowing you to mod your [Bubonico] for even more damage. And with your twin, you can cover the whole map solo.

[Primed Sure Footed] ensures you never get cc'd from knockdowns
[Transient Fortitude] increase ur ability strength to 210% for higher roar strength and lower duration to 166.5% (recommended) but you can replace it with augur secrets for 179% ability strength and 194% duration (not so good) / [Blind Rage] (254% strength, 105% efficiency, 194% duration. It is usable, but you can't lazyman this as much and have to go around picking energy orbs)

High ability duration so you can cloudwalk as a travel mode, its great for clearing missions. Also you won't have to refresh roar too frequently, and your defy can get adaption up without you pressing too often.

Energy Saving option:
[Hunter Adrenaline] and pick Arcane Energize for more lazyman game style or arcane [Guardian] for tough matches, arcane grace if you don't wanna cloudwalk once a long while (i mean it's up to you, and arcane grace will out heal a rank 1 combat discipline turning into a passive heal for you)

If you do not have the formas. do the following changes:

Arcane Energy -> Arcane Grace - this is to mitigate damage
Transient Fortitude -> [Augur Secrets]
[Combat Discipline] rank it up to 5, and suddenly you have 10 extra points.
This reduces the formas you need to 6. and also only 1 umbral forma instead of 2

How to make the above a semi-reality with only 5 formas (This is what I'm using):
1. start off with regular [Vitality] and [Intensify] mods
2. use a maxed [Combat Discipline] at first (you gotta buy 2 [Combat Discipline] eventually)
3. switch out [Primed Sure Footed] for [Power Drift] (which costs less, but you are no longer immuned to knockdown)
4. Now you can slowly forma the rest for your invincible [Wukong]
Current Stats: 166.5% ability duration, 160% efficiency 34% range 200% strength
5. You can make this a 4 forma thing if you switch [Transient Fortitude] with [Augur Secrets] but your ability strength will drop to 169%
