Collect with level 2 ax
If you don’t know where to get the materials, you can look at the right column: dust mites and termite holes
If you are unable to obtain the achievement after making arrows (the same as the video game), it is recommended to restart the game and wait or change to a new gear. Online partners need to pay attention to whether they are console players.
