been stuck for awhile. anyone here i should prioritize for advancing my account?

i’m still pretty early on, moving into mid-game i suppose.

basically my main team (who i use for literally everything) is Kael, Wukong, Tyrant, Gorgorab, and Altan.

i use them for almost all dungeons as well as arena (minus Altan)

i’ve been stuck on Dragon 13 & Spider 10 for months..

would anyone here be worth leveling to help advance me anywhere, especially dragon/spider?

i really have no clue what to do at this point. thanks guys
