So I remembered that Caelon and the Silthion Hybrid were labeled as extremely rare and remember thinking, why aren't they labeled "mythical" like dysons. Then I went on a rabbit trail and got to thinking, what if we had another NPC like those two that when defeated, becomes an ally. Either that or one that gives an artifact that gives you a permanent ability, or both if the ally is the one with the ability. I figured like caelon and larva, it's kind of the same in the sense of trying to find it but different in that it doesn't unlock a mission chain. I hadn't thought of anything specific like stats or ranking up or anything like that, but any thoughts on something like this?

Seems random. All the other allies have very specific paths to obtain, and for the most part are accomplished by specific effort. This would be a lotto grab of when/if you got it.

That said, i like the mythical term and wouldnt mind a series of super rarely occuring mythic rares.

Yeah I thought about that too, about the paths. I then thought about the Darmos ally how it has a specific path, but you just never know when you will get the required legion mission and thus how long it will take. It was actually that which also kind of inspired the thought.
