It's more additional part of my Umbra build

https://overframe.gg/build/114560 Warframe
https://overframe.gg/build/114563 Daikyu
https://overframe.gg/build/114556 [Nikana]

[Exalted Blade] should be used on special targets with Immunity on damage from our main weapon ([Nikana])
It's shouldnt be used when you getting big dmg on face bcs then you will not get lifesteal from [Daikyu]

[Exalted Blade] is preety useless in my build and you should spend your energy more on other spells from my guide.
Any other spell is a better way.

Thanks for your attention.
Have fun
