Amalgam

[Bringer of All] was a skill that allowed Replicus to merge with one of his Apostles. Replicus would also be allowed to take one of his skills – a non-Null Life skill – and throw it into the mix, with said skills being deconstructed, bettered, multiplied into many, unique variants, and used as a further amplifier of the resultant creature from the merge.

This, was what [Bringer of All] had been. 

Skullius had used it only twice. Once in Inhone City and once more on the night he split himself. 

Replicus hadn't used this skill since he hadn't had an Apostle to merge with after the incident with Ferex, and before that, he hadn't had a real need to use it. Because of its 15-day cooldown and 5-minute duration, he preferred to save it as a trump card.

The current [Bringer of All], was different.
