The Achievement: "Stay on the trampoline in the Whistling Grove in Mount Hyjal for 20 consecutive bounces."
How to make it a cakewalk: mount up! After a few frustrating attempts, I mounted my flyer and just flew back to the center after each "bounce" completed and got it in one.
Step by step for the slow:
- Mount up on your flying mount
- Fly to the middle of the trampoline
- The trampoline will bounce you up and then down again -- mounted or not, you cannot control the bounce itself
- Once the bounce completes, immediately fly to the middle of the trampoline, which should bounce you again
- Repeat twenty times for the achievement
Notes:
- Track the achievement as you are making the attempt. That way if it glitches/bugs you will know and can make any needed adjustments.
- The bounce will not always take you all the way back down to the trampoline, so make sure that you when you fly towards the middle, you fly all the way back down to the trampoline.
- There is currently only about a one second period between when the bounce completes and you need to start the next one, so try to figure out which way you need to be moving when the bounce completes during the bounce to make sure you can make it back in time.
Enjoy the fast free achievement points!
Edit: Evidently this thing is still buggy as hell. To confirm, this does work on Icecrown (US).
