U also have to shoot magic at the wall in one quest
Shouts also work, if you mean the quest I think you do, and are not actually magic despite being classed as such for game-mechanic purposes, so even in that case a spell is not required. My stealthy archers, in fact, used FusRoDah to pass that point, since neither of them was using magic of any sort but needed access to said location for a certain side quest.
