I would like to create a monster that have a blindsight of 120 feet and that is blind beyond this radius. Can I give this monster a teleportation action? This action is usually described as follows (emphasis mine):
The monster magically teleports, along with any equipment it is wearing or carrying, up to 120 feet to an unoccupied space it can see.
Obviously this description doesn't fit for a blinded monster. So maybe I could readjust the description as follows:
The monster magically teleports, along with any equipment it is wearing or carrying, up to 120 feet to an unoccupied space.
Does it make sense? Is this in contrast with something in the manuals?
