Ill have to see if I can find something.

This isn't a perfect list because most of those champs are from doom tower or missions.

Faction unity leader champs like Teox can be summoned, but *only* when they're a boosted summon or primal option.

They should modify this list to include a section: "the following champs are no logner obtainable : ..."

Let's see; Ninja, Alexsandr, Ronda, Xena, He-Man, Skeletor, the monster hunters, turtles including april and shredder, predator and xenomorph.

Did I miss anyone?

Oh, and very soon the assassins will no longer be obtainable either

go into the sparring pit, head the the empower champions section, and hit the little info button. it will give you a full list of time limited champions (as well as one off in game rewards like lydia or horse).

oh and skillz, i noticed a tiny error in the description of how empowerment works.

i

 you maybe want to see if you can get someone to fix that?

That's a crazy error to find in-game after all this time. 

I vote that we get it fixed so we CAN empower Arbiter with Dracomorph!

Oh yeah I forgot to mention this to CMs. 

Thank you all for the assistance and information.
