i agree that it's unfair and broken, but just go into online mode and let anyone join. someone will pull out a counter and win for you by themselves, it just happened to me.

in general though, this was a ridiculous den. the present issues with the raid system were insane here, to the point where on my first attempt the timer had reached the halfway point before i was able to use my second move. i think that the entire tera raid system needs an overhaul, because it's just going to keep forcing us to pick hyperspecific counters that aren't really much fun. it would be much better if we were just able to use the pokemon we already like instead of literally having to catch and EV train a new pokemon and get it to level 100 just for that one specific raid to even be possible.
