[Saryn] has a great base kit that is able to deal with almost every type of content in the game. This build focuses on the nuking aspects of her kit but is slightly more focused on single rooms or small tilesets. We subsume an additional buff to push her damage potential further.

Pillage is chosen because it gives you plenty of survivability and a bit of armor stripping. Roar triple dips with Toxic Lash and increases the damage of the rest of your abilities. Breach Surge creates a fairly interesting feedback loop but requires energy support or more efficiency.

Molt should be replaced if you're choosing a subsumed ability. It's fairly weak at pulling aggro in most content and the speed boost doesn't last long enough to cement itself as a solid ability.

Efficiency is fairly low on this build as you're primarily using your energy for buffs that have decent duration, Spores which shouldn't need to be recast often, and the occasional Miasma. [Blind Rage] can be replaced with [Transient Fortitude] if you're having energy issues.

Duration can be traded for more Efficiency or Strength but your energy economy may suffer. It also makes your Miasma no longer last 10 seconds in ESO.

[Augur Secrets] is a flex mod that can be replaced with any of the other Augur set mods or any augment.

Survivability shouldn't be needed as this build nukes the entire map before any enemy can get near you.

Arcane Aegis has a chance to [Protect] you when it procs so that you don't have to use any other form of survivability. It can be replaced with any other arcane to suit your playstyle.
