Kind of confused on how familiars work. What I understand from research is it seems you need to get fams to epic (by using them to level them up + fusing rares to 100) and then reveal the potential, hoping for things like drop rate, boss DMG, or healing?
If they don't end up useful you can extract them for more leveling uptime. You should not be revealing rare or common fams.
Does that more or less seem correct? Thanks!
