wish i new im in the same situation

so you need to hit him with the fire ballson to the lighting up cristals

as ur fighting, u'll notice cerain crystals light up. u can only destroy them as they're
lit. I would suggest using cynder first, because near the end when there's a hole with a
crystal in it, u can just charge spyro's fireball and destroy them in one hit. That's how
I did it.
