[Vauban] was known for his great crowd control but after the rework he's able to do a ridiculous amount of scaling damage. This build specifically attempts to abuse his [Flechette] Orb and Overdriver to burst down enemies all the way to the level cap. We subsume an additional buff to round out our survivability or push our damage even further.

Roar is chosen because it's the most straight forward buff. Eclipse is stronger but requires you to stand in bright light. Shuriken can allow you to deal with high armor but requires an augment slot. Elemental Buffs don't increase the [Flechette] Orb damage. Hybrid buffs like Elemental Ward and Warcy are okay if you're not planning on using the orbs to kill enemies.

Tesla Nervos and Photon Strike are the weakest abilities depending on what you're trying to do with [Vauban]. Replace Tesla Nervos on builds that don't care about additional CC and replace Photon Strike on everything else.

Strength is pumped up so that all of your abilities can come together to do even more damage. You should be able to outpace enemy scaling as long as you aren't dealing with armor.

[Vigorous Swap] buffs [Flechette] Orbs for some reason. A lot of stuff affects it because of how they're considered a weapon for the purpose of synergy with Overdriver. If and when this gets changed, simply replace this for more efficiency or duration.

[Streamline] should be replaced for any augments. Minelayer and Tesla Nervos are very cheap and your energy economy shouldn't suffer very much.

Range is extremely low because it doesn't change the range of [Flechette] Orbs and barely hurts the range of Overdriver. Unless you really need Bastille it isn't worth the slots to increase it.

Arcane Avenger buffs [Flechette] Orbs for some reason. If you don't have the time to proc it or don't want to risk your shield gate then you can use Arcane Arachne or any arcane of your choosing.
