Hey guys, [Mirage] is my favorite frame and I decided to make a survivability build that I could use that is outside of the meta. It is quite expensive (1 aura forma, 2 umbra forma, and 3 regular forma) but works great! At the moment there is no Exilus mod because I ran out of capacity and do not want to forma again.
Obviously the polarities could be changed however you like, They are this way because of my other 2 Augment builds.
I easily went 1 hour survival Arbitration without dying. Its not meta but I personally paired this with my Silva & Aegis Prime build (https://overframe.gg/build/14867/) which can be swapped with your preference of melee to provide life steal to keep this glass cannon alive. I had no problem with Jumping into the hordes of enemies to slay them and survive.
Feel free to leave positive criticism with making this better.
You cast your 1 and then your 3* and keep them always up. Have fun hacking away!
*ATM the Vengeful Charge Ephemera will allow you to have the 530% damage bonus even in the dark areas of the map for maximum damage. I am not sure if this could or will be patched out. For now It pairs well with [Mirage]'s 3rd ability.
