I have seen level 50 mythic armor, and relic, but Never once, on the broker or anywhere else, have I seen a level 50 mythic accessory.

I am just wondering if I am wasting my time hunting for them or not.

They do exist! I've found two Archon's bracelets (not in the same battle, granted) fighting the huge mob of Vorkids (or Myconids, sometimes?) behind the weird puzzle (with the sword and shield symbols) in the Dungeon of the Forsaken. I hear they can also be found behind the first door, where you have to have a pet try to open it, but I've never found one there myself. Makes fighting that awful mob worthwhile, even if sometimes I have nightmares about Vorkids afterwards.

I pick them up occasionally. I've been meaning to write down where I find the different mythic pieces to see if all the bosses have a chance to drop the same items or if it's different. I did start on it before and I do see that the Archon's Bracelet can drop from at least two bosses. I'm not sure if this stuff counts as spoilers or not. If you want I'll message you the information. It's not much though since I forgot for a long time I was going to do this and didn't pay attention.

Awesome, I was starting to give up hope.

If anyone wants to sell any that are not intelligence items, I'm paying 200diamonds. I need six in total. Would prefer str/ag, but I can deal with dex. :P

Krin actually said in a thread that the first two bosses can drop accessories, the dark elf trio drops the armors, and the final boss drops the relics. X3

Awesome! Thanks!

I just got a Mythical Revenant's Bracelet from fighting the Myconid King after the long mob battle. Unfortunately, it is an intelligence based item. Still, that's one area you can definitely get them! Going through that puzzle has benefits!
