Mirage arcane is a powerful illusion spell that:
includes audible, visual, tactile, and olfactory elements
However, the spell description adds:
Creatures with truesight can see through the illusion to the terrain's true form; however, all other elements of the illusion remain, so while the creature is aware of the illusion's presence, the creature can still physically interact with the illusion.
A creature without truesight cannot move through a wall created by Mirage Arcane without destroying the wall. Can a creature with truesight do so?
It seems like the answer hinges on exactly what work the last "can" in the above quote is doing.
