Very tanky damage reflecting build.
A little PSA about how [Adaptation] works, its not 90% damage reduction, it applies as damage type resistance and is based on the highest resistances in your effective health pool. meaning that your shields go from 25% resistances to 92.5% resistances, while health only goes from 0% to 67.5% :-/

You need to make sure your emissive colours give you electric for your ward.
With ward and max over shields, you can [Reach] 7.2k Shields, and with each cast of your pillage stripping over 80% armour and shields you can completely strip in just a few casts (a nidus spectre takes you over 100% strip, this is both good and bad as you can no longer gain shields from fully-stripped enemies)

As enemies are damaging you and you are gaining shields back from pillage, they kill themselves to the electric ward very quickly without you being in any danger.

7.2k shields / 0.075 damage modifier = ~96k eHP

despite other frames being able to get more eHP then don't constantly refill in the same way, and with AEGIS giving shield [Regen] with your 3s long shield gate you can fully regain your shields with the help of pillage before the 3s gate runs out.
