how do you get fuel?

[FoxyLuca2107]

I am owning a lot of minions and really want them to work faster since i can't play much. How do you get fuels to make them work faster?

you can get fuels by killing bosses in Boss world

You can get minion fuel from killing bosses
Diffrent teirs of bosses can give different teirs of fuels
Hope it helped
Have a great day ahead
