who is 60, who is booked, who has masteries

Skullcrusher needs to be in CB

Both CB and arena need to be revamped....what level dungeons are u at

Only two are currently 60, Big 'Un and Bad-el-Kazar, but I can move others rapidly to 60 (this is part of why I'm trying to figure out who to prioritize). Masteries for Big 'Un, Bad-el-Kazar, Anax, Coldheart, and Kael.

Ice Golem: Stage 12

Spider: Stage 11

Fire Knight: Stage 9

Dragon: Stage 15

For your arena team, I'd suggest High Khatun and Warmaiden with Big'Un and Mountain King. It's tempting to try and upgrade from Warmaiden to Roxam, but the problem is, if I'm reading this right, Roxam's AOE decrease defense isn't available on his first turn, which is pretty crucial in arena. 

For CB, you're going to want to lose Kael and Coldheart, to be replaced probably with Skullcrusher and Ghrush. 

For dungeon progress, Scyl is a solid pick for 60, lots of healing plus a revive, an AOE hit with (low) chance to stun and a bit of turn meter control. 

Do you own Frozen Banshee?

Sadly, no, no Frozen Banshee or even Apothecary. 

Thanks for all of the advice so far, and would love to hear if anyone has more!

60 skullcruser (book cooldown)

60 scyl (good enough without books imo)

not sure who would be 5th 60 yet. bt those 2 i would do right away. probably be doing d20 by then lol

Ironically, just a few days after you asked, I finally did get my first Frozen Banshee and am working on leveling her up.
