Assassin/Ninja Help Endgame warring build

Hi

Does anyone know any good builds for guild warring? Preferably using Nirvana but if there are substitutes that's fine.

Archetype doesn't matter much, i'm fine with either acrobat or shade.

Currently using the build from the build guide, problem is it doesn't work much with wars.

WynnBuilder build:
> Caesura
> Aquarius
> Chaos-Woven Greaves
> Stardew
> Yang
> Yang
> Diamond Hydro Bracelet
> Diamond Hydro Necklace
> Nirvana [w6w6w6]

 

for wars you wanna either follow the holy trinity and have a proper pre built team of 2 tanks 1 healer 2 dps

or make a solo build with inbuilt healing such as monster or lament
