Blueprint pieces dropped from Comotosed Soul, Waning Soul and Lost Soul in South Elysium at the Myriad Core. Requires 90+ Novictum I use the Provoked Bond of Novictum that also drops from the afore said mentioned mobs. You can then spawn the boss from the in Incarnator at Monopolis.

I spawned and killed this Pb 20 times.

Difficulty Level: Medium (Updated guide to understanding these terms)
