The series has more or less elaborated on how people within the series can acquire external powers to their own and use them to power up basically. There are two types so far:
1.- The first would be to simply host a power. There are a few instances of this in the series. One would be kallavan with his essence of bravery. Another would be evankhel with his ancient. Aguero with his fire fish is another instance. And the last one I can think of is hell joe with the red bari.
2.- And then there is bam's way which seems slightly different. He basically devours things he runs into and adds them to his arsenal. Both thrysas, souls, black march. As SIU has explained in blog posts the implication is that bam calls out on these powers via his revolution.
So... what is the difference between hosting a power and simply devouring? The series has kinda made the point that bam devouring something makes it an actual part of him however in practice it doesn't seem like it works substantially different from simply hosting a power. Kallavan, aguero, evankhel didn't seem to need to go through the hassle of revolution to use the powers they host. Perhaps the difference is that devoured powers are inherently compatible with the host? Or perhaps a normal being can host just a few powers meanwhile bam can devour as much as he likes?
