Myo

I got Multidimensional to trigger from the very first mission from Unai Kemen, the "To save a thousand worlds" arc. Maybe try that?

at Level 25, the Ouroborous initiation arc will send you back there, you can get it then.

Should be able to run it just fine with anyone that has it unlocked in Ouro, yep!

If you switch to villain, you can pick up the villain Initiation trial from The Pilgrim even if you've already done the hero one. Edit : If not, it should show Ouroborus Initiation under the L50 mission list from the Aspect of the Pillar, even if you're not L50 yet. But I'd check with the Pilgrim first.

Myo. Costume I'm using at the moment. Spent too long on it.

Can't remember where I found a link to this before, but I've been using it for a few days already and just wanted to say thank you.

Paragonian badger? This Praetorian badger can't remember the exact arcs, but since I didn't even start doing them until about level 30, and I got them all from Ouroborus, I wouldn't worry about missing it. Edit : As far as I'm aware, there are no badges you can miss from leveling too quick.

From the Issue 25 patch notes : Heroes and Vigilantes with the Villain Disruptor badge will get a popup introduction to Agent Hassell; Villains and Rogues with the Hero Slayer badge will get a popup introduction to Lord Schweinzer. You must be at least level 10 to access the contacts. Agent Hassell and Lord Schweinzer will now let you pick which Safeguard or Mayhem mission you want to run. You can only access missions when you are at their maximum level or higher (so 10+ for Atlas, 15+ for Kings Row, 45+ for Founders' Falls) and they will set you and your team to that maximum level.

You can do them all in Ouroborus. Don't worry!
