There are between 3 and 6 collectables available on each level of the Deathly Hallows - Part 2. Getting them all is required for certain trophies. Below is a list of all the collectables in the first level of Deathly Hallows - Part 2, Gringotts:
Wandering Part 1 - Sorrow (MUSIC):
This is right at the start of the level. Head to the right and then go past the waterfall and you should see the blue collectable (video time: 00:05).
Challenge 1 - Gringotts (CHALLENGE):
Once you get to the initial set of cover on this level, the collectable is to the right (video time: 00:38).
Ron Weasley (CHARACTER):
Once you are given the message to meet Ron and Hermione at the bridge, ignore them, heading down the path to the left of them up into the cave. The collectible is inside (video time: 00:55).
After you cover Hermione while she unlocks a door for you, and you go downhill, keep an eye out for a vault room filled with treasure. It also has the final collectable inside (video time: 01:15).
