The carriage wheels begin to crack and splinter as the tentacles twist and pull them.<br/><br/>Adrian recognizes the spell as<em>waves of exhaustion</em>, but he's not able to hold onto the bat and he slips off.<br/><br/>{Give me a quick Reflex roll from the bat to see if it's alert enough to turn around and grab Adrian, let's say DC 20, since it's flying and it would have to bank hard to the left or right to grab Adrian before he hits the ground. If he succeeds, then your turn occurs like you wrote it. Otherwise, Adrian falls about 20 feet to the ground. (We'll keep the same Concentration roll, though.)}
