I cannot get past the dragon at Gringotts. I've used the Deluminator to release the first chain, I've made the tricycle, and the first time a trail of studs appeared, but now nothing is happening. I have no idea how to beat this. Help please?
You need to
A) release the second chain by moving the lamps and de- and illuminating them again (up again at the chain post)
B) you need to do all things in the chamber where the trail leads to, collect the cup and the go back to the third chain and release that
