Even though I have most of the coliseum drop familiars already, I'm going to track here exactly which ones I have, and how far I have left to go before I catch 'em all. Thanks to [url=https://www1.flightrising.com/forums/gde/1419000]Maki's guide[/url] for the list of which familiars drop where.
Feel free to use this thread as a template for your own if you like. I have an imgur album with black-and-white versions of the boss familiar icons [u][url=https://imgur.com/a/dR0Tnq8]here[/url][/u].
