Honestly? With how her 3 gives her crit chance (that also effects her abilities) it basically invalidates the need to focus on her passive. You’ll still get some benefit out of it from her abilities, but, eh, the fact that her 2 is a basic grouping ability (good to have at worst) and her 3 and 4 are essentially irreplaceable means 1 is just by default on the chopping block.

Additionally, while I’m here, forget Tharros Strike. Subsume Pillage onto Gyre. She needs both Armor Strip -and- survivability, which Pillage provides both of in spades as she is one of the few frames who just naturally builds enough power strength to hit Pillage’s breakpoint (which Corrosive Projection greatly lessens). Attached below is an example of my build. Energize is for QOL and basically unnecessary after her 3+4 get a safe buffer of kills , Molt Augmented can be replaced by some strength shards and another arcane to your taste. I have two energy max shards, 1 +max energy filled on spawn shard, and 1 Parkour Velocity shard on, but, again, those are to your taste and effectively QOL.
