What's Behind that door?

The "Door" is on the back of the auction house and is by far a great challenge to overcome because of all of its trials and the excessive resources to overcome them and the fact missing one thing could result in having to get all the items again

The "Door" is locked and will need the Copper key to open.

TRIAL 1-2:

These consist of one man asking for a item to cross the lava pit, Trial 1 has a man asking for lemonade and Trial 2 has a man asking for a lemon popsicle.

TRIAL 3:

A tall jump that requires cosmic sand or condensed joy.

TRIAL 4:

A scary door that requires you to eat brazilluim beforehand.

TRIAL 5:

An overheated metal door that requires coolant to operate.

THE END:

This is the end, where 3 rapidly regening copper sand Veins which for some god forsaken reason can't be picked up with a metal bucket.
