# Can a creature burrow through walls or ceilings?

Burrow allows a creature to move through solid stone at one half its burrow speed. Does this also allow a creature to move through non-floor surfaces, such as walls? Could a creature with burrow travel through the city walls into a city?

Does burrowing through vertical surfaces allow vertical movement? Could a creature with burrow move into the city walls, then up to the allure behind the battlements?

If a creature can burrow up a vertical surface, can it also burrow through a stone ceiling? Could it then drop down on an enemy below, or travel up to the floor of the room above?

See this closed question for prior discussion on the topic of burrowing.

Yes

The Burrow Speed is analogous to the other Special Movement Modes, Rules Compendium, p.202, like Fly Speed and Climb Speed

There is no restriction that it is only horizontal movement

Burrow speed A creature that has a burrow speed can move through loose earth at a specified speed, and the creature can move through solid stone at half that speed. The creature can’t shift or charge while burrowing.

@Soulrift: Most walls and ceilings won't be made of loose earth. – Zachiel Mar 3 '13 at 18:40
@Zachiel Agreed ... but the Burrow speed still allows them to go through solid stone at half speed – SteveC Mar 4 '13 at 12:30
Yes yes it was just a reminder for Soulrift ;) – Zachiel Mar 4 '13 at 17:54
