Помогите, пожалуйста, с переводом:
1. When activated, the unit displays the presence and location of any spirits or ghosts within 30 yards. If focused on a specific spirit, it can also magnify the image and display a representation of the spirit's appearance. The DSU also contains a spatial translation unit that allows the use to communicate with any nearby spirits. This spatial translation unit can emit specially focused pulses of virtual particles that attract the attention of any spirits or ghosts within several miles.
Как перевести spatial translation unit? DSU, если что, это dimensional sensory unit.
2. MET: A DSU can detect ghosts on its own; as a two-Trait Talisman, it needs to win or tie an Arete Challenge.
Как перевести выделенную часть предложения? Arete Challenge в MET - это что? Это не просто уже бросок Арете?
