maulie, royal guard, and seeker are all good options.

from the champions you haven't levelled yet, gorgorab and doompriest are both amazing and steelskull is also quite good.

Should l level up gorgorab and doompriest to 6 star prior to the others?

I would certainly do gorgorab first. His aura makes him extremely useful in arena, where it's best to have all your champions at 60. Additionally, you're currently lacking in good revivers, which is a hole he fills easily and as a reviver you'll want him at 6 stars for maximum survivability.

Doompriest, on the other hand, will carry you through both ice golem and dragon and is great in arena offense, but depending on where you are in the game, she can persist at rank 5 for a while. She's definitely worth bringing to 60 at some point, but unless you're having severe trouble keeping her alive, she can wait for a bit before being ranked up.

Thanks for your input Carpe.

I think you can complete arbiter missions with those champs, dungeon progress  should be your focus.  Gorgorab #1 for sure.

He has Sethallia... so Doompriest is even less of a priority. With Gorgo, Sethallia and Maus Mage available as support options, I don't really see any reason to build Doompriest at all anymore, nor Steelskull, except for FW. 

You have so many insanely good Champion.

You can't get rid of any of them .

You have 2 Royal Guards.

You are going to have to level them both up to level 60 for Dragon Speed Farming.

You have so many good champions.

I would be here forever telling you about them all.

The only hero I would consider using as leveling Food is the Bone Keeper.

You own 3x Bone Keeper.

I would keep 1x Bone Keeper incase a Fusion comes which requires it.

I would use other 2x Bone Keepers as leveling food

Than I would live in the Campaign for the next 3 months if I was you. lol

You need almost all of those heroes level 60.

You have 30+ heroes which need to be level 60. lol

Thank you everyone.  You've helped me before Trips on guidance.  

Player J.  Funny you should mention Bone Keeper.  I noticed l had three and already used the two lvl 1 BKs to level skill.  I didn't realize l could use two Royal Guards at 60.  I rarely use RG for anything.

L9..  Mausaleum Mage was my go to in the early levels.  I just raised him to 6* to meet mission requirement as he was my only decent one for that Affinity. 

What J said is correct, you have so many good champs I don't where to start...lol

Just keep farming and you will be through arbiter missions in no time...

I got lucky with my last pulls.  On 20 ancient shards l got 6 epics including Gorgorab and Doompriest (although DP is less of a priority it seems).  :-)

If you are ever looking for a new clan, we are on the verge of taking down unm daily but accept members of all levels so lmk.  Only boot people after a week of inactivity without notice.

Not sure l would be much on the value added side considering l need to attach Brutal 3 times to get Grandmaster Chest.  haha    I do play regularly every day though.  :-)

where u at in dungeons?

I messaged you.  Off to prepare lunch.  Thanks for the help. 

Fair point, i'd forgotten about sethallia, so doompriest's stock is lowered a bit, but i'd hardly say that makes her not worth building. Her value in arena alone makes her worth using.
