I was on my chacrater last night and respec'd myself, when I re-did my build I noticed that I'm not able to summon more then one clone, despite having 12 passives in bunshin mastery. My chakra isn't the problem either it was 2k so that should be adequate.
Can you try again on the latest version and see if it's still at one clone Wolf-Bloom
Zeno put 18 passives and only summoned one clone as well
Ight probably still a bug then
