I agree with the majority that you would start falling right away.
The question I have is on a power like the Avengers "Crimson Stride":
"You stride through nothingness, appearing at your enemy’s side to make a deadly attack. Then you stride away, carrying your foe with you.
Encounter
Divine,
Teleportation,
Weapon
Standard Action Melee 1
Effect: Before the attack, you teleport 5 squares to a square adjacent to an enemy.
Target: One enemy
Attack: Wisdom vs. AC
Hit: 2[W] + Wisdom modifier damage. You teleport 5 squares and then teleport the target to a square adjacent to you."
If you teleported 5 squares -up- to a flying foe, do you get the attack then,
as the power states, or would you immediately start falling, and miss the
attack? Would the last part of the power be negated then?
What if you used the teleport adjacent part to teleport to a square *above*
the flying foe - could you then get a chance to hit? (or heck, ultra cool factor
here, ride the thing!)...
Thanks!
