Hi!
This is a [Guandao] build for High level. It is based on the armor reduction with the [Shattering Impact]. This build is good against armored enemies, and also good against shielded enemyes, even against level 9999
I use it with a Helios Prime which include the 3 Gladiator mods (+30% crit chnase/combo)
And with my Magnetic based [Kuva Nukor], with 4 status: (magnetic, Heat, Radiation, Viral)
The Viral should be the highest one
The usage is simple:
[Nukor] the enemy, and stack the slash on them.
Further more i recommended to use the Naramon focus schoole, to keep your combo counter high.
You might not see high numbers, but high level enemis will also fall against it.
