I've been trying to figure out when/why sometimes during boss runs everyone gets 4 tokens instead of the normal 3.
Is it predictable? I think so... But what are its mechanics?
So far I've done a bit of research (ok, perhaps more than just a bit...)
*note: everything on elite, full clear, from mission lobby, solo
In order of when they were done:
40 roarmulus twin runs, all at 3 tokens each.
1 snarbolax run, 4 tokens
2 jelly king runs, 4 tokens each
1 roarmulus twin run, 3 tokens
1 vanaduke run, 3 tokens
15 roarmulus twin runs, 3 tokens each
1 snarbolax run, 3 tokens
