Potential System, halp

Let's reiterate:

Potential Scroll (70% or 90%): This ONLY gives the item the "unidentified" tag if it works. It does nothing else. Adds no stats.

Using a magnifying glass changes "unidentified" to any 1 of: Epic/Rare/Unique. Depending on which of these rankings you get, the stat boosts you can get may be higher (with unique offering the highest stat boosts).

If you don't like the stat boosts you have, use a miracle cube to go back to "unidentified". This let's you use another magnifying glass to get a chance at another boost.

You will only ever need to use 1 70/90% potential scroll (according to our local KMS source). The boosts you get are always random. You do not get better boosts for having reidentified X amount of times. You could start with really high +% luk boosts on one identification, but then get really low +%str boosts the next time.

If this was targeted towards me, my question wasn't fully answered, but I do apologize for my misuse of words. I'm interested in the mini-buff skills specifically and how they are obtained. Would I need to keep using cubes to reset my equipment to unidentified and then use a magnifying glass and hope I get one of those boosts, or is there something more to it?
