How do you lvl 290? My max is lvl286
Power-ups you can unlock with yellow tokens can increase the maximum level of your heroes.
What yellow tokens? It says max
From Home -> Fit Tower -> Powerups -> Advanced Powerups
Once you progress with the advanced Powerups there will be a “Hero Level Capacity” to be upgraded with the Legendary Runes (the yellow ones)
Thank you for the detailed information
