BloodAgel Set

How do I unseal the BloodAngel Set?

To release the BloodAngel set, the player will use a sealed part of the set and a Ancient Hero Soul in the Chaos Machine

In "Regular Combination" the player just needs to fill in the parts of the sealed set that he wants to release, after that he just clicks on combine and removes his item from Chaos Machine. This combination has a 100% success rate.
