I love augment mods with passive and active effects. (4) Rising Storm: Blade Storm attacks increase your melee counter by 4.
You can use this with Arcane Trickster and be invisible forever! Thanks to teleport low energy cost, you can spam this as much as you want~
(3) Fatal Teleport: Teleport will perform a finisher on the target, dealing 200% extra damage. It’s… nice? It makes Ash a bit of a support, I guess. (2) Smoke Shadow: Smoke Screen conceals allies within 15m for 8 second. AND you put shuriken on any frame thanks to helminth, so you can strip armor with any frame! (1) Seeking Shuriken: Makes Shuriken strip 70% armor for some 8 seconds. I feel like some of them are kinda… pointless? Could be already part of the ability? Some frames REALLY can’t waste a mod slot for a minor quality of life.
