This is meant as a Progression guide, using this build as a starting point and evolving on it as we get better mods throughout the game.
Baby's first [Saryn] build good against enemies up to level 60 or so.
This build assumes that you've farmed [Saryn]'s pieces from Kela De Thaym on Sedna and therefore completed the Second Dream and have access to Energizing Dash in spoiler mode.
A mod that can be "difficult" to get is [Regenerative Molt], it comes from Red Veil or Steel Meridian.
You have to be max reputation level with them to unlock warframe augments. This can be skipped by buying it from other players with plat.
Power Range: [Saryn]'s Number 1 most important stat! Power range affects the spread range of spores, the more enemies you have marked with spores the more damage you'll be doing and the faster it stacks. This will also affect Miasma's radius. Using [Stretch] and [Augur Reach] will give us enough range to get by for now.
Power Strength: [Saryn]'s 2nd most important stat. This will effect the upfront damage of Spores, Toxic Lash damage and Miasma damage along with the healing ticks from [Regenerative Molt]. Right now all we have is [Intensify] which is a little lacking tbh. This will change once you farm some corrupted mods.
Power Efficiency: This is [Saryn]'s 3rd most important stat. This lowers our energy costs across the board. We supplement 30% efficiency with [Hunter Adrenaline](Gain energy upon taking health damage) and Energizing Dash from Spoiler Mode.
Defense: [Saryn] has decent defensive stats but nothing crazy, so we need to help her out as much as possible. Running [Physique] and [Vitality] will make our health pool rather large at a respectable 1038(This will fluctuate depends on any team members running Physique as well.). Steel Fiber will make each health point worth more HP and Regenerative Molt will give us on-demand healing for 35 energy.
Primary Weapons: These can be whatever you want to use! With this game being a horde [Looter] shooter, I tend to prefer Area of Effect(AoE) weapons. Some early examples would be the [Ignis](Wraith) at Mastery Rank 5 and 9 respectably, (Kuva)[Ogris] at MR 9 or the [Lenz] at MR 9 as well!
Secondary Weapons: I tend to use AoE secondaries as well, some early examples are the [Atomos] at MR5, [Synoid Gammacor] at MR 7 or a [Gaze] kitgun!
Melee Weapons: I often play melee focused. I also slot more healing in my melee weapon, simply cause we can use less damage mods on melee as tehy scale with the combo counter! For a combo based build here's my Broken Scepter build for early/mid game.
