Fantasy Westward Journey was an online game where players could obtain equipment and props through various missions and activities in the game. The reverse scale was a high-level equipment in the game. It had strong defense and attack capabilities and was known as a battle artifact. However, if a player's account brought a set of reverse scales but did not use it in battle, there might be the following reasons: 1 Reverse Scale needed to be paired with other equipment to be of the greatest use. In Fantasy Westward Journey, the matching of equipment was very important. Different equipment needed to match different attributes to play the best effect. If the Reverse Scale was not matched well with other equipment or its attributes were not suitable for the current battle, it might not be able to play its role. 2. Players may need to level up or increase their levels to unlock more equipment and skills. In Fantasy Westward Journey, equipment and skills needed to be upgraded. Different equipment and skills required different upgrade conditions. If the account had not been upgraded or the upgrade conditions were not enough, it might not be able to play its role. 3. The player may have encountered other unexpected situations in the battle, causing the equipment to not be effective. In Fantasy Westward Journey, the battle process was very complicated. Sometimes, there might be other unexpected situations such as being attacked, being counterattacked, being controlled, and so on. These unexpected situations might affect the effect of the equipment. If the player had brought a set of Reverse Scales but did not use it in battle, they needed to carefully recall the equipment's matching and usage conditions or wait for the game to update to improve the equipment's effect.
