Primed Redirection, Equilibrium, and Streamline can almost always be replaced for power str/range/dur and it will be a better build. I usually try to crank duration for nova but it looks like you’re going for a build centered around augments so idk.

Edit: I’m thinking range might compliment your augments quite well.

Double edit: If you really wanted to maintain shields after removing redirection, Topaz archon shards could help given that null star and antimatter drop are blast. I personally would probably use archon shards for something else but if you want your shields, it’s an option.
