Str - [Gauss] needs 100% str for 100% damage reduction with 100% redline. Any more is fairly mediocre damage on your abilities.

Dur - Very important for being able to get and maintain redline. Your main stat.

Eff - 130% is nice for when you want to fully buff yourself. It is not worth sacrificing duration for more as it will reduce 100% redline uptime.

Range - Many people [Sacrifice] this. In steel path it does provide excellent cc as well as armor stripping and [Condition Overload] damage with your 3. You will have a lot more energy to be able to use it against higher damaging enemies.
