so here is how she works:
due to your hight efficiency and [Assimilate] you can use your walk and use weapons during your 4th ability
so basicaly: use your 4. and feel free to go in hord of enemies (use shift for a faster mooement)
dont hasitate to use your 1st ability to strogest enemy you see and he will fight for you for 80 seconds
i reccomend you to replace 2nd ability (use helminth ) wich ability ? its just on you, i reccomend [Firewalker] ([Nezha]) for faster shift dash, or vital [Rush] ([Lavos]) for a dash with 5 sec cd.)0energy drain

Weapons:
primary: use something with hight damage and aoe like: [Kuva Zarr], Kuva Brama, [Acceltra]
secondary: dont matters
meele: im using [Kronen Prime] with soviegin aura due to fast combo moovement (not reduced by [Assimilate] )
but you can use weapons like [Nikana Prime] with [Blind Justice] for fast moovement ( w + block and e)

enjoy your immortality
!!!!!!!!!!!!!!!!!!!!! YOU ARE IMMUE TO EVERY STATUS AND KNOCKBACK SO FEEL FREE TO SHOT A BRAMA ARROW RIHT UNDER YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[Vitality] and [Preparation] are fully replacable
Have fun
