@GodlyVlad Coldhours is right. It works exactly as in the trailer. As soon as it touches compatible ground or you press the ‘fall to ground’ and it comes on good ground you teleport.
Someone on reddit claimed the same thing, even going as far as to hold the trailer next to his vid and saying it doesn’t work. Until it was mentioned that the bracelet probably ended up in a crack or somewhere loba cant teleport.
