This guide will provide you the quickest way to get ssgss and ssgss evolution in Xenoverse 2. Just go through the guide and follow step-by-step instructions.
The first thing you will need to do is to complete all the lessons of Whis and make sure that your level is more than 90.
After that, you have to go to Play Data and head over to the instructor info. Make sure that the total training level of Whis is maximum.
Then choose the Jiren character and select the Sky stage. Once the fight starts, you will need to know that this form will drain your Ki but it is strong.
And then you will need to have Whis’s and Vegita’s friendship to be maxed out as well. Select the God of Destruction Beerus character and the Planet Namek stage to start the fight.
Head to training settings, bring the Ki to normal and CPU Status to AI (Normal).
This form has an even bigger Ki drain than ssgss but if you have a good amount od Ki, you will be fine.
