Shard to the Rescue tips needed

[tazmad]

Has anyone got any tips for this mission to get gold, Seems everytime I do it I get so far and then a Hasfient (or what ever they are called) is stuck way back from the pack & I have to fly a mile back to be able to get to it which wastes alot of time. The other thing that happens is it is hard to do it in the time frame, I know it is possible because I did it in 8:33 and the target is 8:30. I have spent almost 3 hours on this 1 stage and haven't come close to that time again.

Finally done it with 10 seconds to spare, I ended up using the last battleset as it built up prowess faster and has a better attack. I tried Diamond Dash but found it worst. Thanks for your help.
