Squeezing

[nogoodscallywag]

Wondering if this is doable...

A hallway ten feet wide. Can a large creature squeeze through the hall on only 5 feet? For instance, an Orb of the Void is on one side of the hallway occupying once square. Can the person, who is large, bypass it by squeezing onto the opposite side of the hall?

[Nefreet]

Yes.

They would of course be at -4 AC and move at half speed while doing so.

Yeah, that ten-foot-tall ogre isn't actually ten feet wide, even if he does have a huge belly. The five-foot or ten-foot square is just a convenient game device to allow relative positioning of different-sized opponents.
