Surpassing 15 Star Tyrant Equip

oh I miss that base equipment stats so you only lose 50 base stats and 30 attack per equipment however the 3 set effect cover some part of

but getting to 22 star will grand you additional attack and stats which I believe atleast since it 160 gear it preset is higher than tyrant which is like 16 star +10 attack 17 + 11
18 star + 12
19 + 13
20 + 14
21 + 16
22 + 18

you will have +94 more attack once you reach 22 star

I'm 99% sure it remembers

 Spoiler

Or else the stats on this wouldn't be so high

that isn't proof of anything cuz you don't know what type of ee or starfoce he used also kms has additional option potential
