Actually, I disagree with Ramzi. You
CAN enter Davoi's wall if the orcs are aggro on you. I mean it worked fine for me, either it works the same way for all of us, or I got the really "special" copy of the game. However, you do have to be:
1. Very, very fast.
2. Very, very lucky.
Basically, if you look at what's happening to you when you try to click the wall while an orc is hitting you, you'll see a message about "event skipped". This means the orc smacked you before you could trigger the animation of you walking through the wall. You will get "event skipped" even if you have stoneskin up and the orc hits you, because the game engine is playing the "orc hitting you" animation instead of the "walking through the wall" animation. (This is exactly the same thing that happens if you try to read a Stone Monument text while a monster is trying to hit you, if you feel like testing it out somewhere outside of Davoi). If you're fast enough, however, you can sometimes get through the wall while the orc is beating on you, just as long as he doesn't land anything while you're walking through the wall.
And yes, I have verified this by entering the wall while having a Bowshooter pincushion me from across the room.
Arrow hit me, I dropped target on the orc and switched back to the wall, clicked the wall, passed on through, next arrow hit me. Ranged attacks are very slow, however, and that probably accounts for my success. Point is, it's worth trying, because getting through that wall sure beats having to be tractored through and raised.
