Using rubies to reenter several dungeon of pieces for upgrading tier of yal heroes until enterance fee rise upto 200 rubies.
Dont use any costs for buying heroes.
You can hire'em in the inn.
If you wait, yal gonna get'em. Just be patient
I recommend you to change heroes
Dont pour the recource on them ( except the PRIST.)
Knight : he is not a good indeed.
MAGE : same
Asaassin : if you want
Also you can get heroes in the inn.
Jus act like entrepreneurs.
