Stats as in level or skill level? :) Depends on what you're trying to max out!

For skills, if it's a sealstone daemon or daemons with similar skill names (eg: Sleeping Beauty (Summer) has the same skill name as Hare of Inaba) you can farm their magatamas or fuse daemons of the same type (eg: fuse Wind Weasels into Wind Weasels) to max out skills! :D

For rarer daemons where skill name is uncommon, the only way is to hope you can re-summon that same daemon and MAX out the level of the second daemon before fusing it into the first. (eg: to raise Amaterasu's skill, summon a second Amaterasu, max that second card out and fuse it into the first Amaterasu for a 100% skill raise)

As for maxing out levels (not skill levels), again it depends on the type of daemon you're going for. Fusing 4-star magatamas (ie sealstone magatamas) is usually the easiest and fastest way! Tengu and Kaguya (no skill) sealstones give a little more exp than other sealstone daemons, so you can farm those, though Hare of Inaba is usually quicker to obtain.

For raising Phantom daemons though, farm all daemons at story 1-1-2 for a faster raise in addition to farming 4-star mags.

Hope it helps, but you can ask more if you want! :)
