one of the fun things in this game is reroll champions.
i think some of the mechanics here can improves such as:
1.when same hero visit tavern >free< reroll. why? because even spending scyee, it could be getting same hero again.
2.when existed hero visiting the tavern, players get the option to transfer legacies without killing the existing champion. why? because some of the champions had gone through multiple transferred legacies, and level up, so they had to skip the recruitment, even is high star champion is visitng the tavern.
