Lua  is  a  good  epic  worth  leveling  to  60,  elhain  is  strong  for  early  to  mid  game.  high  khatun  is  usable  till  end  game.  

my  suggestion  is  use  high  khatun  for  speed  aura.  Lua  for  aoe  nuke.  Maybe  old  hermit  for  attack  up  or/  warmaiden  for  defence  down.  And  add  additional  aoe  nuker.  Could  be  elhain  or  athel.

once  you  have  a  better  squad,  you  can  definitely  use  skull  crusher.  

but  for  now,  6  star  Lua  first.  

In order to get to Silver Arena, I think it is best to have at least 1 level 60 hero.

The level 60 hero will be your damage dealer.

You don't have a level 60 hero at the moment.

I think you will struggle to reach Silver in your current state.

What you need to do is focus on Campaign till you have a 6 star champion.

You need to level up food champions to be sacrificed to make a 6 star champion.

(Don't sacrifice any of your Epic or Rare heroes as food - You will need them later)

Level up Common or Uncommon Heroes

You have 3 heroes in my opinion which could be very strong damage dealers.

- Lua

- Pitiless One

- Athel

Each 1 of the above hero's offer a different strength:

Lua is the best Arena Nuker because she hits the strongest out of the 3.

Pitiless One is the best Campaign Farmer/Nuker because he has built in Healing + C.Rate Aura.

Athel is the best Clan Boss Nuker because she does the debuff Weaken.

All 3 of these heroes can be Campaign Farmers.

All 3 of these heroes can be used in Arena as a Nuker.

All 3 of these heroes can be used in Dungeon's as a Nuker

I have already told you there strengths were they excel at.

The decision on who to 6 star first will be up to you.

Pick the hero you like out of the 3.

Level the hero you pick to level 60.

Than come back to the thread and ask for help in Arena when it is done.

Thank you for that. I'm going to be leveling Lua first to 6 star, it will just take time. Thankfully I have a couple 5 star chickens! lol
