Strange is making a very good target for the wyvern, as he tosses fireball after fireball at the creature. The fire is doing some damage, but the thick hide of the creature is negating some of the effects. The wyvern roars at Strange and skitters forward...however, it's caught by the magic. The tail is still lashing like the wyvern was trying to knock Syrlya over, but it's slowed down and definitely in pain thanks to the magic.

"Idiot!" Strange calls out, as tosses one more fireball at it. "You said you'd only see what it is, not attack the damn thing by yourself!"

Because why else would Syrlya be so close to the beast?
