Your speed becomes 2. This speed applies to all your
movement modes, but it does not apply to teleportation
or to a pull, a push, or a slide. You can’t increase
your speed above 2, and your speed doesn’t increase
if it was lower than 2. If you’re slowed while moving,
stop moving if you have already moved 2 or more
squares.
Pretty straight forward, slow effects everything, but Teleport. The change is to speed (so look at speed if you are not sure what this means). Note creatures with an actual Swim, Burrow, Climb, etc speed can still run while slowed.
