It may just be a brazil server problem... Although others have him and can use him fine.. But for some reason I cannot upgrade him. Wasn't sure if it was a problem on both side or if I need a higher reitsu to upgrade him. He is on his base form and I have a reitsu of 27 and I can't get him up at all. If it isn't a problem here, I'll just try and contact the brazil team, but wanted to check here first.
i think u need a minimum level of reiatsu before you can upgrade your zanpakuto..... so focus on boosting ur reiatsu to 40 before you can max upgrade ur zanpakuto
