Obtained by opening boxes, exchanging, etc. The details are as follows:
1. Open the box: The blue hammer is one of the rare items in the box and can be obtained by opening the "special box" in the game. However, due to the high rarity of the blue hammer, the probability of getting it by opening the box is relatively low.
2. Redemption: In the game, players can obtain in-game points by accumulating game time, participating in activities, etc. When the points reach a certain amount, they can be exchanged for rare items such as blue hammers in the game store.
