I was just subsuming what I haven't yet because I wanted to try out Golden Instinct. Turns out, it's really nice. And it scales off of ability range (up to around 480m with my default Loki build cuz range is his thing, go figure). Already found a rare crate and 3 or 4 ayatans in between 7 and 10 capture runs so far.
Now that Helminth is maxed again though, I may stop subsuming for now. Don't know if they're going to add more ranks in the future or not.
Aside from max leveling Helminth however, I really wanted to get a Banish Decoy build working on my Loki, but for some reason the mod from Conclave "Deceptive Bond" which is supposed to give Loki 50% damage redirection to Decoy and vice versa isn't working. My theory was that banishing a decoy with that augment running would just give Loki a 50% DR for decoy's duration as long as you don't get nullified. But I'm sadly not able to test that out, since the key mod doesn't seem to work outside Conclave. (Don't know if it works in it either, as I haven't been able to get in a match. You know how it is)
