Can barrier techniques allow a body to phase through matter?
As I was watching Danny Phantom. I recalled that cursed spirits can actually phase through matter. Which made me wonder if a sorcerer can do the same.
Energy can phase through matter. And from what we saw from cursed spirits in the first episode and later in the serie, we can infer that cursed energy can also do the same.
Because barriers are made from cursed energy, and a sorcerer can use them to control space and time (domain expansions and Sumo's barrier for instance) I think they remain the best way to achieve this. But still is this possible?
