Surpassing 15 Star Tyrant Equip

Is there a difference? Let's assume Star Force, then.

there is a diff star force has a preset on each star

reg ee or aee is random stats

if you using starforce it all base on the level of the equip
I don't know what is the preset for 160 equip on starforce

however I believe it like this for 160 gear

1-5 star + 5 stats to all per star
6-10 + 6 stats to all per star
11-15 + 7 stats to all per star
15+ star is like MEE preset stats


~ALSO let say you have xfer 15 star tyrant gear to sweet water gear
it will become 14 star and with the same stats as the 15 star tyrant gear and losing it superior item set
which mean you can use starforce on it
and let say tyrant cape the stats using primes scroll + 15 star tyrant is + 205 to all and 180 attack
the new sweet water gear is also + 205 stats to all and 180 attack with 14 star

now use star force and you fail and you lose a star it now 13 star
your new sweet water gear lost it stats base on preset of it gear since it gear isn't a superior item it wont lose stats base like tyrant
the new stats will be like something like 13 star +198 to all and 180 attack
