Awakening and Velocity with non-headshot focused secondaries - this is for headshot Spirex build. For better synergy with QT, potentially switch an arcane with energize.

This (untested) build focuses mainly on range to make better use of the synergies between her 1, 3, and 4 (and hopefully more synergies to come). The arcanes and her aura focus on pumping up her passive because of how heavily she will rely on Merulina. The lack of survivability mods is due to the intent to use QT&Merulina in tandem to keep her alive, and since she has to keep moving for her passive the hope is that she will take less damage, and QT+[Primed Flow] (and a panzer running [Martyr Symbiosis]) will save her should she falter.

If for some reason you decide to use this, good luck.
