Items of a single legion can only be worn by people belonging to this legion, but you can apply to transfer to the legion you want for a month. After the transfer, you will temporarily lose your previous rank and regain the lowest rank of the new legion.

For example, if you transfer the highest level of Double Snake to Black Nest, you will become the lowest level of Black Nest, but after you return to Double Snake, you still have the highest level of Double Snake.

Your military ticket will be frozen until you return to your original legion.
