Is teleporting a creature considered forced movement of said creature?

Question

Is teleporting a creature considered to be forced movement of said creature? I have a player interested in a power that adds damage on forced movement and teleport.

Answer 1

No. From the compendium:

Forced Movement

Movement that a creature is compelled to do, specifically a pull, a push, or a slide. A creature can be moved in other ways, such as through teleportation, but only pulls, pushes, and slides are technically forced movement.

Answer 2

It's not forced movement, but per the Player's Handbook errata, trying to teleport creatures into dangerous terrain or to a spot where they will fall gives them an immediate saving throw to avoid the teleport.

Teleportation

Page 286: Replace the text for the Destination entry and the Immobilized entry. This change addresses what happens when a creature is forced to teleport, and it clarifies that the Immobilized entry includes restrained as well.

✦ Destination: Your destination must be a space you can occupy without squeezing. If arriving in the destination space would cause the target to fall or if that space is hindering terrain, the target can make a saving throw. On a save, the teleportation is negated.
