Awhile ago, someone posted proof that they won a Champ in Hero Trial. I think the odds are extremely slim. Since Hero Trial was released, I've only seen proof of two people winning a Hero, a Champ and a Succ.
Yes, very low odds. My thoughts are that that the same hero three consecutive times might be the trigger to win the free hero
Does anybody know the exact chances? one forum user claimed 0.1% - but not for all L# I guess..?
I've been doing L12 (Paladin only) for a long time now and even though I've faced 3 Paladins in a row never won anything but the minimum possible reward of 1,200 HB. I think the chances are greater if you beat a tough hero, like PD (someone from my guild did that and got Witch as a reward which is a cruel joke...)
MH.
i did L2 for very little time and won my AC. Ive been doin L3 since then and seems like forever and never won anything. like since trials started.
