[Gauss] has a sprint gimmick that's usually only good for memes and funny YouTube videos. With the Helminth system we can actually make it have a purpose by putting on Fire Walker to quickly cover the entire map in fire. This also protects you and your allies from status effects.

Fire Walker is chosen because it's the easiest movement speed bonus to handle and has the added benefit of giving us status immunity. Infested Mobility and Molt also work but they require you to spend a lot more energy in their upkeep. If you run higher ability strength on them your movement speed scales so high that you become nearly uncontrollable.

Duration is maxed because it has an interesting interaction with Redline. The buffs scale off duration instead of ability strength. Abilities that drain battery have a slight negative synergy with this depending on how you're using them but the massive QoL increase is worth it. It also allows our subsumed abilities to have more duration.

Ability strength isn't touched. You don't need any more ability strength but Kinetic Plating doesn't give you full damage reduction if you dip below 100%.

Armored Agility and Speed Drift are both flex mods. You really don't need that much sprint speed for most content outside of the open-world areas. They can be replaced with more survivability, more QoL, or augments.

[Rush] increases our sprint speed. This synergizes well with his passive to build battery meter. It can be replaced with many other exilus mods but the easy option is [Vigilante Pursuit].

Arcane Phantasm just plays even more into the sprint speed gimmick. It can be replaced with any other arcane to suit your playstyle.
