INTRODUCTION

This build is a DPS focused [Vauban] build used mainly for endurance steel path missions e.g. Survival or Circuit. Bastille is used for crowd control and armor strip while Flechette Orbs from minelayer are used to do DPS that scales with enemy level (multiplied by 1+enemy level/10), at a faster rate than enemy HP scales. In addition, ability strength (2.83x), Vaubans passive (1.25x), overdriver (1.46x), [Vigorous Swap] (2.65x) and arcane arachne (2.5x) are all multiplicative damage buffs for [Flechette] orb. This means at level 101, each [Flechette] nail deals an average damage of 235,000 viral damage while at level 9999, each nail does an average of 21 million viral damage, which increases to 90 million after 10 stacks of viral status (created by nourish). Keep in mind a level 9999 corrupted heavy gunner in steel path only has 1.9million health, meaning a single nail will one-shot an armor stripped level 9999 CHG.

Alternative options are to use Arcane Avenger to increase [Flechette] orbs Crit chance to 95%, and [Tek Collateral] to boost the crit muliplier to 4x, but this will require you to run Combat Discipline, and possibly equilbrium with dispensary instead of spectrorage/spectrosiphon to both heal and get energy - see TwistedBolt's crit version: https://overframe.gg/build/270804/vauban/minmaxed-one-man-killing-zone/ . Also see booben's version which inspired this build: https://overframe.gg/build/417663/vauban-prime/boobens-flechette-dps-vauban/

UPDATE 2023
Nourish applies Viral Damage to Flechettes AND gives an energy multiplier of 2.83x, meaning Energize gives 424 energy per trigger, energy orbs give 70 energy per orb and Archon Stretch generates 6 energy/s when Tesla Nervos is used.

Archon shards: Use two amber cast speed and three duration or strength shards

UPDATE Oct 2023
With shield gate changes, we now require Brief Respite and Augur Mods to regenerate sufficient shields for shield gating. With Brief Respite, Augur Reach and 1-2 augur mods on pistol, a cast of Bastille now generates 418 shields, which corresponds to approximately 1.5s shield gate.

PLAYSTYLE

1. Cast Bastille to suspend enemies and strip armor (Note: never hold 4 to cast vortex if you want to strip armor - if a vortex becomes active, Bastlile will no longer strip armor). Armor strip also works against acolytes even though they don't become suspended. It will take around 5.5s for a full armor strip. Instead we can use Magus anomaly to draw enemies into the bastille range (Anomaly has a 30m pull range while Bastille has a 23.5m capture radius). An alternative to armor stripping is to use Vortex (Hold 4) and shoot [Latron] Incarnon or Unairu Caustic wave into the ball.
2. Toggle ability 2 and cast overdriver on the ground and walk over it to receive weapon damage buff, then toggle to [Flechette] orb to ready it
3. Wall latch to activate Arcane Arachne if equipped (optional) and activate [Vigorous Swap] (optional) by swapping primary and secondary (don't use quick melee due to a delay), then immediately lay down a [Flechette] orb. Repeat [Vigorous Swap] and [Flechette] orb up to 4 total orbs. If playing circuit, you can skip these two entirely by picking up decrees that boost damage (and are additive to arachne/vig swap).
4. Lay down Tether Coils which have a range of 47m which will slowly draw in additional enemies outside the range of Magus anomaly/Bastille/[Flechette] orbs
5. Hold 1 to charge 4 tesla nervos

BUILD SPECIFICS

Duration
Required for uptime on spectrorage, bastille and [Flechette]

Efficiency
Dumped due to [Blind Rage]. Make up for energy economy with [Primed Flow], Nourish, Achon [Stretch] and any other sources such as [Grimoire] [Xata Invocation], emergence dissipate, [Dethcube] [Energy Generator] etc

Range
Important for Bastille range, Tether coil grab range and nourish [Retribution] range and vortex range should you wish to collapse your bastilles

Strength
Important for Bastille enemy capacity, armor strip rate, [Flechette] damage and overdriver boost

Flexible Slots
[Augur Reach] and [Umbral Intensify] are flexible for [Vigorous Swap], [Augur Secrets], [Augur Message], [Tesla Bank] or Repelling Bastille

Exilus
PSF is best in slot.
Flexible for handspring, cunning drift, power drift

Arcanes
Energize - sustaining energy with spectrorage and 45% efficiency
Arachne - +150% damage boost to flechette orbs after wall latch
Avenger - flat +45% crit chance to the base 50% crit chance of [Flechette] orbs

Archon Shards
2 cast speed shards
3 duration shards
