So I am confused as to magic involving the astral plane. From what I read and understood mages can't attack people in a plane different from them. So if they are astrally projecting they cannot attack people in the physical realm? My friend says that they could still attack in the physical plane using mana magic though. If they are allowed to attack the physical realm from the astral is there any protection for a team without a mage?
Example: A mage is astrally projecting himself, and found us. His astral body is behind a concrete wall, while his physical body is somewhere else in the world. We have an adept who can see in the astral plane, but since the mage is floating behind a concrete wall it is impossible for the adept to touch him. We can't outrun the mage since he moves around the astral plane at the speed of thought* (Not sure how fast this is, but since neuron transfer is .2ms it must be very fast). At this point is the entire team screwed because our team doesn't have a mage?
Side question: Are there any other planes? If we assume that there is the astral plane, physical plane, and the technological plane. I was wondering if there was another lesser known plane.
