3. Party members continue to attack after apparently Isgebind returning to the ground, attacks performed by party members, but on my screen there is no Isgebind, and I can't target any enemy.
4. Wait for Isgebind to return to the sky with attacks flying across the arena again, I forget what it's called.
5. Isgebind returns to the ground and is on screen again. Finished duty without further invisibility.
