Welcome! Thanks for checking out my [Saryn] Build~ She's one of my favorite frames to use!

Build information

[Saryn] is a great AoE DPS frame, along with satisfying buffs and melee dmg. The most notable things about this build would be Shooting Gallery replacing Molt, and the usage of [Venom Dose]. These two altercations allow me to always run endgame content and maintain my damage for long periods of time in Endurance Runs. Having a lot of range, Shooting Gallery is an amazing CC that also increasing you and your squads damage. [Venom Dose] makes up for the lack of power in this build, since spores already scale I figured that I wouldn't need a ton of power and I would rather be able to deal more damage with my weapons.

Without Arcane Energize, Zenurik, or [Energy Siphon], I am able to maintain a reasonable amount of energy to apply my buffs. As a player who jumps solo into squads, I like to buff those around me but remain very useful, versatile, and strong to be able to solo all content.

For a cheaper build; Replace both Umbrals with the normal variant, along with [Continuity]

Tips

Any Aura mod works, I personally take [Growing Power] to help make up for the lack of Strength. Some addition options could be [Energy Siphon] or [Steel Charge].
Any Arcane is fine, but for what I do this is what I prefer. I do not run attack speed mods on my melee, hence Strike, so I can open up a slot for Primed Expels. To help with shield gating, I take Aegis, but [Guardian] works quite nicely as well in combination with [Adaptation].
