Surpassing 15 Star Tyrant Equip

Testing could be done with a single star tyrant.
The bigger question is who has Sweetwater Capes to waste.

It should be relatively easy to test whether Star Force remembers pre-enhanced stats or calculates them, though. Blowing up any equip enhanced with (A)EE's will tell us that.

If you blow up an equip with an (A)EE, the item will get destroyed and that's that, it only produces a trace of your equip if it blows up from Star Force.

Also, as far as I can tell, AEEs add the same stats as Star Force (so, fixed stats now, except for the attack/magic attack scaling with the weapon's attack/magic attack)
