Is unlocked at level 80.
Increase 50% of growth rate additional and basic attributes after advancing once.
Increase 100% of growth rate additional and meanwhile is improved the quality of partner.
So if the spanish translate is good Tavern Uryu 380% of growth rate, and 2nd is 430%, for example.
actually its the stat growths. Like hiki has an agi growth of 5.3 it would be 7.9 or 8.0 after the 1st upgrade and then it would be 10.6 after the 2nd upgrade

i reject the thought that ONLY tavern partners will be eligible for upgrade... just sayin
why reject it ? there wont be new tavern partners but
the event partners are every month or even in 2-3 weeks.
I dont see why event partner should be upgradable when you should buy the new event partners .
They wont make tavern better than zero div partenrs so calm down .
I hope they add same feature for SWP partners. I doubt they add it for event partners trough, cuz it will cause massive disbalance. If you can counter a 5.5 agi growth with ~4.5 agi one if you stack, you wont be able to do it against 11 agi one.
