How to get experience for characters in general?

[Della_frost]

hello, I've been playing for a long time and I'm stuck, I have all kinds of gold, silver diamond and tons of bronze characters, but I can't level them up, and I only have one with a maximum of 2900, if someone suggests a way to level without being the olomesa or playing prize games I would appreciate it, because I've been weeks without a breakthrough and I'm getting tired although I love the game itself, as I said I'm stuck and my average strength is at 1500 with some gold, so I can't use a character maxed to level others, I would appreciate the help.

Por favor no me borren el hilo, o díganme si hay otro sitio donde pueda consultar, todas las guías que e visto son para gente con otros personajes ya leveados y yo no yego a eso, encerio por favor me encanta el juego pero no quiero seguir el tiempo perdiendo.
