"Awakening potential Acquired"

[Renfield]

is it like a free upgrade if you do safi a bunch of times? or its a whole another awakening other than the one from smithy

It means that next time you try to add a skill to Safi weapon it has higher chance of being a rarer one. It's exactly the same thing when you don't choose any skill and "store potential".
