The reason why you can’t pick up the Aether Tool is because it is designed with a specific limitation. The purpose of the Aether Tool is to upgrade the rarity of the weapon that you are currently carrying. This means that if you have a common or uncommon weapon, the Aether Tool will enhance it to a higher rarity level, such as rare or epic.
However, the Aether Tool has its own limitations in order to maintain balance within the game. Once a weapon has reached the highest rarity level, which is Legendary, it cannot be further upgraded. Therefore, if you already have a weapon that is at the Legendary rarity, you won’t be able to pick up the Aether Tool because it would serve no purpose for your current weapon.
This limitation ensures that the game remains fair and prevents players from constantly upgrading their weapons to an infinite level of power. It adds a strategic element to the game, where players must carefully choose when to utilize the Aether Tool to maximize its effectiveness.
I personally find this limitation to be an interesting aspect of the game. It forces players to make decisions and be strategic in their weapon choices. It also adds a sense of progression, as players start with lower rarity weapons and gradually upgrade them to more powerful ones.
The reason why you can’t pick up the Aether Tool if your weapon has already reached the Legendary rarity is because it has a limitation to prevent overpowered gameplay and maintain game balance.
