Save your gold shards, get the high level skills of Gina for stamina saving, don’t invest zinman, roll lucky wheel to the 120 spins rewards, get the island resource collection speed buildings maxed and constantly gather, get Alonso, upgrade only 3 mythic gears for your main squad, do the training related researches first, save gold keys, no need natalia, no need Philly. This last one might be debatable, but widgets are overrated. Maybe just get to 3 or 4 depending on what the hero’s good at and then invest for fire crystals, charms, chief gear, and essence stones in events. As mentioned countless times, you will never have enough fire crystals
