If I got this right, we do stuff like dungeons and when we get enough soul thingies we will be able to upgrade it?

I love it if that is how it works.

We can use this thread to discuss and tell eachother what we have found out about the upgrade.

I did roulette trial and got Garuda HM, seems everyone else had the same thought so we were 8 ppl all in our shiny ilvl 105+ gear and beat Garuda so faast haha

When we beat her I got the text "Thyrus Novus emits a gentle light." so it is working.
I assume harder trials give more to the progress, it would be a way for older players to do EX trials again.

Now I need to go so I can't try doing a dungeon but please share anything you've figured out here!
