Stag knight is a great champ, cant go wrong with him for general content, if you want to work on clan boss then i would look at getting a reliable attack down who has attack down on the A1 (coffin smasher stands out for me)

I can see the champs for a good clan boss team actually but im not sure what you are running already

Edit, just seen you have vogoth, i dont have him but those who do rave about him.

Are you using Ninja for campaign farming? If you aren't, I would suggest you max either Sinesha or Bellower, so you can speed farm Brutal 12-3/12-6.

After that, I would go with Stag Knight, Vogoth, and Zelotah. Zelotah is a fantastic arena lead champ, only really replaceable with Rhazin (and, of course, Lydia).

Stag Knight great for spider 20 and fk 20, and pretty much everywhere for where u r at

How dare you forget Pyxniel?! 😂

Or the void legos of course - Warlord, Nekhret, Siphi, Urost all have more powerful resistance auras as well.
