Heyo lads! just a few tips on this guide to appeal to anyone reading this, so thanks if you´re checking out my guide!
Riven can be replaced by Sacrificial Steel/[Gladiator Might] (lowers dps significantly)
Sadly, this build may fall off a bit in dps against level 600+ Corpus enemies in Steel Path.
Now, some of you less serious tenno may be asking about [Primed Reach], to maintain optimal and sustainable damage numbers, above level 200, mods that don´t affect damage output can seriously put a dampener on the effectiveness of your [Guandao].
if you´re looking for a much more variable build, say for use against corpus, i´d suggest the Yunchang´s Blade Build by UltimoFive, seen below
https://overframe.gg/build/98346/guandao-prime/y%C3%BAnch%C3%A1ngs-blade-guandao-prime/
where he goes way more in-depth about this build and what it entails, as well as providing 4 different builds, all without rivens.
i wish you all the best, and best of luck to you fellow Tenno!
