Urost, Toragi and Vergis can each solo him with decent gear
Edit: Apologies, I hadn;t actually checked who was eligible at the time I posted.
I just did it (slowly) with frenzi the cackler and greenwarden ruarc in a bloodshield ring
Follow-up edit: It just occured to me probably any champ could solo it with a destroy set, a bloodshield ring, and the emergency heal blessing
Note - I used a bloodshield ring though id imagine it would have worked fine without.
Bloodshield rings too rare, smh. F2P advice only thanks. :D
Really though, just about anyone works if you have some Bloodshields. OP, could you share a screen of your available champs for that level?
