I ran the 2P Persona dungeon many times and this guy never spawns on FL3. So I switched to 3P, since he has his own floor, and have being running 3P for the last three days and I can't get him to drop his card. I got a dozen blank cards... but no King Frost. I put some blank cards up for trade on both of my accounts for a King Frost. However, if any of you have a spare Frost and want something else, PLZ let me know. Thank you!!!
