Easiest way to get a 6* awakening gem?

Asdsdsdsd

Been trying to awaken my AA for a while and can’t seem to dupe him but let’s just say I don’t have unit finances for a lot of content

Easiest way is with units on Black Friday/July 4th.

Without that, there is no easy way. Farm units/revives and 100% Act 7.
