To level up quickly without using Dragon Balls (DBs) or experience potions, focus on completing quests that offer significant experience rewards, especially those that are suitable for your level. Engage in grinding at high-density mob areas to maximize your kills per hour, and consider joining a party to increase your kill rate and efficiency. Additionally, using buffs from your skills or items can help you gain experience faster. Prioritize quests and mobs that align with your strengths as a water-fire character to optimize your leveling process.
