I have been trying to get TB for a long time. Did 7.1 100% and explored all the new variants as well. But my t5cc luck was just trash and couldn't get the right t5cc i could use.
So there were two options left. Either to explore act 6 or complete abyss. Pulling Aegod just made that decision much easier.
I did the abyss in the space of 3 days with the following team.

The worst fights for me were invisible woman,cyclops and mordo in descending order. Took me a total of 3.2K units to do it.
Now the rewards:

Got skill t5cc and had to choose between falcon,Elsa and masacre. It was really tough for me. Just kidding. I took falcon straight up.

Then I remembered I had a 6 star ag crystal as well and the odds were great and I duped my falcon.

Very happy right now π
