This is my endgame setup for [Gyre]. Please note, this is a modified variant of Kyaii's [Gyre] that removes the need for Arcane Energise and Zenurik. Watch Kyaii's video for a great tutorial of how the build functions.

Archon shards: 1 purple (electricity ability damage), 1 tauforged red (strength), 2 blue (energy max), 1 yellow (casting speed). Note if you can keep arcane [Ice Storm] up you can go for 2 purple. Alternatively, you may prefer molt efficiency to arcane [Ice Storm].

Why [Equilibrium] instead of [Flow]? [Synth Deconstruct] on your pet will produce a decent amount of health orbs. Additionally, if you combo this with [Blood For Life] you will always have energy and even if you lose it you can regain it instantly.

Companion recommendation: Hound or Diriga can help with intial ramp up as they can proc archon stretch for you with synergized prospectus/[Arc Coil].

Focus school recommendation: madurai for easy access to increased strength and cast speed, but really any focus school works with this setup

[Grimoire] and [Nidus] specter can be used to further push your max strength.

Edit: updated to my current build. This variation has much greater survivability and works as an insane weapons platform as well as a nuke frame. If you find the low duration too difficult swap arcane blessing for molt efficiency
