Info:

Total Eclipse applies the effects of Eclipse to the clones which means each clone is getting that 500-900% damage buff from Eclipse.
2 of your clones will fire your currently equipped gun, all 4 of your clones will use your melee weapon.
Your clones will almost exclusively draw enemy fire.

Gloom is here for healing on any damage dealt, which is constant.
Gloom could replace your 4 instead, I put it on my 2 because this build cannot fit a Explosive Ledgermain build.

Yes, there is a mis-polarized mod, this is reflective of my actual build and is only there to allow diversity in builds like adding [Primed Flow], [Enemy Sense] for Index, or [Vigorous Swap] for Profit Taker. This build is the "true build" but everything still fits.

Stress Testing Info:

This is my main [Mirage] that I've played for years.

Build Stress Tested for 30 minutes of Solo Lua Conjunction and I really enjoy Solo Steel Path Void Cascade on this build.

Nearly exclusively used to Solo the entire Steel Path Star Chart while using exclusively Akarius. (Used Nyx + Akarius for Interceptions)

[Akarius] is my main weapon and is stronger than Simulor in terms of total damage, just click in the general vicinity of your enemy and they'll die.
Try using your mini-map in the large mode to see where your enemies are more quickly with the large [Enemy Radar] provided by the aura mod + [Animal Instinct] on your pet.

[Synoid Simulor] makes a [Singularity] after a single trigger pull on [Mirage], [Mirage] also gets WAY more active singularities than anyone else, theoretically can have up to 19 singularities.
This weapon can be spammed (hold the trigger and don't let go) almost infinitely for a large AoE with limited range since [Simulor]'s projectiles have a maximum travel distance of ~30m or something like that, but its a 9m spammable AoE.

[Pennant] and [Hespar] are used to drop tons of slash procs instantly using Initial Combo heavy attack builds exclusively.
Gloom slows any nearby enemy down to 5% speed which is perfect for setting up heavy attack builds.
I use [Pennant] and [Hespar] on [Mirage] to kill Steel Path Void Angels in 1 or 2 heavy attacks.
