Up to five further Heroes can be added to the mining party to assist the lead miner. Their contribution to the party will be based on their STR and END scores, mining score and on whether the Hero has mining as their main profession. As individual Heroes are added to the party, the total amount of JEWEL that the party can unlock will update. Once the group's total unlockable amount reaches the maximum unlockable amount, adding further Heroes will not increase JEWEL rewards further, although those Heroes can still receive Gaia's Tears, Shvās runes, and Yellow Eggs.
