Getting Nether Boss traits?

[gachi is manly]

So I noticed that Nether bosses have three different trait items. How does one acquire the second and third Nether Boss traits?

Like for example I got the Katarina's Asylum trait when I beat it the first time but I see there's also Katarina's Guidance and Return traits that i'm assuming you also get from the same boss somehow.

Gaining access to each Nether Boss' 2nd and 3rd trait items will require you defeat them the 2nd and 3rd time, respectively.

You fights the nether bosses in a cycle. You'll unlock more materials in later cycles. Also unlock a new set of super bosses after the 3rd cycle.

The set was from the second cycle. 3rd cycle only gives you the one superboss, although he's admittedly the superest boss in the franchise returning so that nobody else tries to claim his title.
