Can you trigger an enchanted violinist's ability more than once per turn assuming you have enough dice?
Also, if the violinist is exhausted due to counter attack or opponent's ability, can you still use the ability then?
you can only activate each violinist once each time the trigger happens. as long as you have the dice to pay for it.
when you are exhausted you can only use inexhaustible abilities. I don't have the card to look at ATM but I pretty sure the ability can not be used while exhausted.
