Currently on the Test Server the Master of Martial Arts is available for 6,999 gems.
When he was first placed there last September he was priced at 30,000 star coins along with his friend the The Legendary Veteran. I hope that BB has placed him on Test for gems so that people can try him but that when he comes to production servers he is again available for Star Coins. Otherwise it asks the question whats the point of Star Coins.
