i encountered a few minutes ago a champ, i have never seen before. he isn't presented here in this guide and he isn't present in the hero altar. due to him i lost a arena match, i already thought to be a sure win. but then he sprayed some shoots from one mapend to the other and my last 3 heros standing - all of them the same lvl of that mysterious hero - died!
and then,I built a second altar,I spent 150 gems foro hiring another hero but I got the same hero at the first level but I can't select him opening the second altar..I'm in trouble..:S thanks for any answer!
