Although the base game is free, players who don’t want to grind for features have options topay for more items. Because this game is PvE, players who pay to advance won’t harm anyone playing without paying. In regular Hearthstone,bundles are available for real moneyand give the player more gold and mercenaries.
Hearthstone Mercenaries use mercenary coins as their currency. Players are able to obtaincoinsthroughpurchases, but they must be careful.Mercenary coins are unique to each mercenary.Thus, if a player has Sylvanas' mercenary coins, they cannot use them to empower Jaina.
Thus, buying them at all is a gamble, but feel free to use cash if you have it to spare!
