Battle Mages

From BoardGameGeek:

Choose your Battle Mage, ready yourself as you enter the Selek Arena for a fight to the death against some of the most powerful champions of Thargos! Each Mage has an edge in their own magic art. Pit your wits against others as you add to the power of incoming spells and redirect them to your opponents but beware of rare magic that can change the outcome in the blink of an eye. This is a place of dangerous and volatile magic where only the strongest survive. -description from the publisher
