>>104052342>Yeah Phasing and intangibility are definitely up there on the "most difficult powers to use irl" listit would probably be easier to phase if you were already immortal with no need to breath. But if you are immortal then phasing isn't as useful.
One common weakness with phasing in fiction is that the person is basically holding his or her breath while intangible, and how long the power lasts depends on when they were forced to breath again. It also makes them weak to drowning.
