Although the Mechanical Cloak is exquisite, it doesn't have any practical use for Li Yao. Being an engineer himself, he can easily enhance an ordinary cloak with parachutes and gliding wings.
Moreover, now that he has a propeller, which is far more useful than those things, and with his skills, even falling from high altitude won't kill him.
When it comes to a drop that could be fatal, the cloak wouldn't be of much help either, so Li Yao does not want to put it on.
Even though it's slightly better than his own attributes, the small difference is negligible for Li Yao, and wearing it would be a waste.
But it's a different story for regular players who haven't learned engineering.
Many secondary professions have their own unique products, which can only be used by people of that particular profession.
Even for general products, learning the corresponding secondary profession also grants bonuses.
