To maximize your characters' potential, you'll often need to farm for experience (EXP) and gold. Good farming spots include areas with high enemy density or enemies that drop valuable items. The 'Nest of Evil' (post-game) is an excellent source of both EXP and rare drops. Early game, the 'City of Haze' sewers with Mermen can be good for quick EXP. For gold, focus on enemies that drop expensive items or use the 'Gold Ring' accessory to boost gold acquisition. Repeatedly defeating bosses in Boss Rush mode can also be an efficient way to gain EXP and earn valuable rewards. Remember to equip items that boost LCK to improve your chances of rare drops while farming.
