The right place to look for familiar info. And equipment, in the future.

This tool provides info about Familiar and Equipment. (Equipment is in Beta, Familiar is really complete)

P.S.: The search is powerful, it works for both the table and the additional info that appears when you click on a familiar card (See the last pic, the Legendary one - the monsters that had Rarity; Legendary were the only to appear after the filter).
