Good vs. Evil

Just some random wizards I made, for some random other-world I dreamed about (which I can't remember much of--except for some of the awesome fight scenes and duels like this one).
It's about a young wizard destined to save the world they're in, and along his quest, he makes friends and allies (he starts out alone), until he and his friends were able to form a resistance and build up and army (but some of them die, sacrificing their lives for him).
This scene is THE duel.
By the way, their staffs have these sort of stones that produce fire. Sacred fire is yellow (or orange; the stone is white when unlit) and has a yellow aura when in the dark (the aura is invisible in daylight).
Unholy fire is blue and has a purple aura around it as it burns (the stone is black when unlit).
