Forest Dweller

He flies into the sky, the ice walls vanishing. You feel yourself being thrust upwards into the sky. Elos's eyes glow bright yellow.
"HYYYYAHHH!" He screams, shooting countless thunder bolts in your direction.

You realize the ice skill you have won't work here. As you can only summon a block, it would drop before you had a chance to do anything. The only way to use it is if you got on top of Elos, where it could crush him from above.
Fire scorching the skies might work, but the lightning is fast. You'll need to deflect it somehow. Luck could be your answer, but it could also be your demise.

You feel a new skill at your fingertips...
Mirror!
You put it out just in time, blocking the strikes. Strong mirrors surround your body, protecting you. The lightning is repelled back at Elos!

Elos laughs, sucking the lightning in.
"Pointless!" With that he flies forward and breaks one of the mirrors in half. You fly away to avoid the rest, and bring the mirrors down.
It seems like the mirrors can only reflect lightning, and his own lightning won't work on him.

Your only options for this battle are luck, fire, and mirror. Luck could do just about anything.

You decide to make the first move. You remember that you're not on top of him, so ice will not work. Mirror is used for defense, and you're on the offensive here.

Fire or luck?
