RME Won From Bonanza

I had heard the weps won from bonanza cannot be upgraded but I haven't been able to find where this info came from or if someone just started rumors. Can anyone provide a credible source on this?

I don't have any source but I can tell you right now it's untrue, it would be far too ridiculous to be true.

What you might have heard was of someone unable to do the Magian upgrades because they had never started the original Mythic quest which requires all the assaults, eye patch etc. I remember this being a complaint a while ago when someone tried to go from 75 to 99. Not sure if it ever got addressed by SE, but assuming you have the mythic req's done you should be fine. I hope this helps you with your answer.

Haven't checked yet

Ohh that might have been it but the ones you can win now are level 85 I think so it shouldn't have that same problem, right?

When ilv119 REMs were released there was a problem with mythic where you needed the cutscene associated with the weapon to upgrade it.

So you couldn't upgrade from 99 to 119 if you won it from mog bonanza or were in middle of another mythic. As far as I know that has been fixed.

There was never a problem with trial of magians and upgrading a mog bonanza won item though.
