So I ran into an epic red room (without the chronometer I know but still, needed to scout it out)
BEFORE YOU RUN IN!!!
DO NOT USE 2*S YOU CAN USE YOUR WHOLE ROSTER HERE. ITS BASICALLY IMPOSSIBLE WITH 2*S
Paths.
There are a number of paths. Here are photos to help
You start here

Here are the possible paths:
As you can see the class AG is of one class only (luckily didn’t want a cosmic. I’m looking for skill here)








The path I have already taken had a 22k Nick Fury. Probably the worst defender on the map.
The boss is a 24k Red Guardian with no extra nodes, quite an easy fight imo
PLATINUMPOOL!!
Yes he makes an appearance here! He ambushed me just before the boss!

Upon beating him I received this email in my in-game mail

Then from beating him I gained this crystal. I got 50k gold which is not bad from a 10 second fight.

Summary:
Easy to understand layout, some paths have hard defenders, Red guardian boss, Pltinumpool ambush! And remember BRING IN THE MAIN TEAM NOT 2*S
