If you're a fan of RPG games, you already know how crucial weapon upgrading and refining are for advancing through tougher levels. One of the key takeaways from the gear information, such as the Hunter Longsword at Lv.1 with common rarity and stats like ATK and REFINE, is that incremental enhancements can drastically improve your combat performance. Based on my experience, it’s essential to prioritize upgrades that increase your attack speed (ATK SPD) and base damage (ATK) since these directly impact how quickly and powerfully you can take down enemies. For instance, focusing on upgrading to Lv.3, Lv.10, and eventually Lv.15 as shown in the OCR content not only unlocks better stats but may also unlock additional weapon functionalities or bonuses. Don't overlook the importance of rarity and the dismantle option; sometimes it’s smarter to recycle older equipment to gather resources for more valuable gear. Inventory management also plays a pivotal role—keeping weapons and pets like Spore Jinni or Hermit Crab deployed and favorited strategically can give you an edge in battle. The practice of refining weapons continuously, as evidenced by refinement options in the game, can yield marginal upgrades that accumulate into significant advantages over time. Refinement often improves durability, attack, and sometimes elemental effects. Finally, balancing your focus between weapons and pets ensures a rounded approach to gameplay. Pets with unique stats and deploy options further complement your fighting style, enhancing your strategy. My personal tip is to experiment with different pet deployments and weapon upgrades to find the perfect synergy that matches your play style.
