Surpassing 15 Star Tyrant Equip

I guess the question is whether the item "remembers" its stats before Enhancing, and puts those in the Trace,
or it calculates them by decrementing the stars.

If it remembers, you will lose the Superior enhancements.
If it calculates, you won't.
Personally I believe it calculates. Especially as there are items around that already have some stars from EE and no Trace kept.

I'm 99% sure it remembers

 Spoiler

Or else the stats on this wouldn't be so high and other stuff.
