Intro

Works best as solo farm. Hits daily cap by stage 11-12 without boosters using one Lua lens on Saryn or stage 8-9 with affinity booster. Idea is to balance Strength and Range after having enough survivability and energy restoration in the build. First 45 seconds of every stage after the first gives a convergence orb (up to x16 affinity according to wiki) so this is where most of the affinity gain is obtained.

One key thing to note is that sustain is missing from the build, so [Life Strike] on melee weapon (or another source of reliable sustain, such as [Hirudo]) is needed. A decent heavy attack spam build will one shot pretty much everything up to round 12.

Without Umbral and Aura Forma (i.e. [Physique], [Vitality] of [Transient Fortitude] instead) this works as a 2 Forma build with less tankiness and duration.

Survivability

Umbral Vitality + Adaptation + Arcane Guardian - enough to survive. From experience Umbral/[Steel Fiber] generally does not work as well as [Adaptation] at higher stages (though still works).

Arcane Guardian makes up for the lack of an Armour mod.

Energy

Streamline + Hunter Adrenaline + Arance Energize - [Streamline] offsets the [Blind Rage] penalty a fair bit and allows more reliable Miasmas in the first 45 seconds in early rounds, where energy management is tight. [Hunter Adrenaline] allows energy to basically always be full in later rounds. I consider both of these mods too useful for consistent runs to drop.

Energy Orbs can really help during the first 45 seconds in earlier stages, and there is nothing much better so Arcane Energise fills the other Arcane spot. Double Arcane Guardian works too.

Range

Overextended + Stretch - would be nice to fit in Augur Reach, but difficult to balance strength and range with it.

Strength

Blind Rage + Umbral Intensify + Power Drift - [Blind Rage] is basically mandatory with [Overextended] on the build. Without it the build up is way too slow, and the first 45 seconds of each round is key. [Umbral Intensify] is the next best thing.

[Power Drift] over [Cunning Drift] in the Exilus slot as the 30% chance to resist knockdown can be useful. Handspring works too.

Aura

Corrosive Projection - Yes Spore already strip armour, but this will allow slightly faster kills at the start. Anything to pump the start of each round. Can be swapped for anything else useful. As I run this with a Life Strike heavy attack spam build, Swift Momentum has also worked pretty well for me.

Rest of Loadout

Zenurik - Naramon is nice for the 45% melee affinity, but the vast vast majority of kills are from abilities so Zenurik is used for extra security on Energy with Energizing Dash.

Smeeta Kavat - Double affinity on [Charm] could save a stage if it procs during the first 45s on Stage 5+. Happens every now and then. Also quite hard to kill with Health/Armour link and (Primed) Pack Leader.

Weapons - [Life Strike] heavy attack spam melee and a fast firing primary gun to break nullfier bubbles.
