Good Concept on the 1v1 without casting of spells, but it would be wayyyy to imba in combat. Think if you were a Fed Priestess vs. a Techies? Every Time he would die without a doubt. If this were to be coded, the time in combat would have to be reduced to under 4 seconds, and the price would have to be increased dramaticly. A good idea would be to put 3 charges on it, having to re-buy the recipe once all charges are used, it will make the user have to think before they use, as it stands, T-Null.
