"It's easy, if you wait for a little longer, the cooldown for your ability should be over. With it being in that state, it should be quite easy to destroy its soul. Once you do that, it will just become a high valuable corpse. Once that happens, you store it inside the space ring"..
"I'm telling you that because that dark ghost's body is quite special and will be quite useful to upgrade the Demonic Puppet later on" Amon instructed.
Wait for the cooldown of his [Wave of Annihilation] to get over was easier said than done. It has been quite some time since he used the ability as such; it should come off cooldown soon.
However, there was no guarantee that the demonic beast would not snap out of its state before that. If that happens, it would be the case of him biting more than he could chew.
That said, if he wanted to gain something, in this case the Special Dark Ghost, he needed to take that level of risk too.
