Talk:Iso-8/@comment-1301375-20140814051948

Is there any easy way to collect a lot of Iso-8 in a short period of time without spending money? I've been grinding the training levels to raise my characters' levels bit by bit, but it's taking forever. So far, my strongest character (Thor) is at level 22, and it's taken me weeks to get Iron Man and Black Widow up to level 20 and hawkeye and Storm up to level 18.
