Enough Strength for 100% strip on gaze when using some combination of minor outside str buffs such as Corrosive Projection/Growing Power, Molt Augmented(only needs ~80 kills to be enough), Zenurik/Madurai, Archon Shards etc, while having max range or near max depending on the exilus you want, and has decent enough dur without sacrificing other stats to not have to worry about recasting too often.

Roar to buff the 2s damage, be a better damage buff than the 1 and also affect allies.

[Rolling Guard] can be swapped out for some other defensive mod if you want, like [Vitality], something else like [Quick Thinking] given the low hp and high energy with p [Flow], or upgrading to [Umbral Vitality], but that'd need more forma. Or you can swap the aura for [Brief Respite] to go for a shield gating setup.

You can use PSF if you're worried about knockdowns or [Cunning Drift] if you want that extra bit of range and 1 more gun from the 2.

[The Relentless Lost] might be an option instead of [Blind Rage] as well if you're fine with switching the mode often.
