If you die during a boss battle, you get no tokens.
On a gate, I did entire rom battle with some other like 2* guys.
I died in the end, they wouldn't revive me, and they all got 3 tokens, while I, THE GUY WHO ACTUALLY DID SOMETHING, didn't get crap.
If you die during a boss battle, you get 0 tokens.
That's harsh.
I was also 4* and needed the tokens for Polaris.
But instead those newbags got them.
