In D&D 4e, teleportation is very common. Does it require line of sight?
An Eladrin wizard is being attacked with his back to the wall. On the other side of the wall is the room he came in from. Can he teleport through the wall to a space on the other side?
If teleportation does require line of sight, how is it different from other movement except for the following:
- It ignores terrain.
- It does not provoke attacks of opportunity.
