An Eidolon [Titania] setup. Focused on max power strength and enough efficiency and duration to not immediately use too much energy to not be able to deal damage with [Dex Pixia] before energy runs out.
[Enemy Radar] is used to spot vomvalysts quickly in order to take care of them in operator mode, [Power Drift], [Transient Fortitude], [Blind Rage], [Augur Secrets], [Umbral Intensify] and [Umbral Vitality] are used to increase the raw damage of [Dex Pixia] in order to maximize how little time it takes to take down a limb or the eidolon itself. [Narrow Minded] is used to counteract the negative duration from [Transient Fortitude]. [Fleeting Expertise] and [Streamline] are used to counteract the negative efficiency from [Blind Rage]. Both efficiency mods are one off the top in order to fit the entire build into the frame.
Arcans are Arcane Velocity and Arcane Precision. Arcane Velocity speeds up how many bullets hit the eidolon at once, artificially increasing the damage the exalted pistols deal. Arcane Precision, when shooting the eidolon's head, will increase the raw damage of the [Dex Pixia] by a large amount, making it a perfect arcane for the build. There are no survivability mods apart from extra health from [Umbral Vitality], so be careful.
