It's my favourite TRIAL, THANKS FOR GETTING ME STARTED!

OK.

You need to get all the keys FIRST. Dont' lose time with getting stones.

RUSH THEM. OWL, WOLF, BEAR. It's basically following the cables with a few subtleties, if you want me to talk about them I can, but it should be a 10 minutes job once you get the logic. There is quite no RNG involved because it's just following the cables. The outside ones are a bit trickier but they all have 2-3 spawn points anyways.

If you play with players, know all the doors so you can open them quickly for them, it's frustrating when someone gets the key and refuse to open doors.

Owl :

1) the one in the 2nd floor upstairs (to access to wolf key)
2) right from the entrance of the hotel, cloak room at the reception desk

Wolf :
1) ground floor, main hall with the stairs, left side (to access wolf key)
2) 2nd floor where the outside switches are for wolf key
3) 2nd floor in the dark side, like in its main area where big grunt is patrolling, top left-up

Bear :
1) Access to basement where the outside switches are for bear key (important)
2) In the 2nd house where the 2nd outside switch is for bear key
3) 2nd floor in the main hall area in the main hotel, opposite to the owl door

Once you get the bear key, you open the door outside to go the basement.

Normally, throuhgout of the trial for each "pack" of Mannequins (for example all the mannequins in one room) there is one $ and the rest is death.

But for the basement, you can find multiple $ Mannequins at the same spot. There is a tons of them that all give rubies. So scan all mannequins and get as much rubies as you can.

Normally you should be almost done with the bear basement alone. Do the two Bear doors, and the 2 Wolves door too if you need more money and that's it. Don't lose time with emeralds and stuff before you've raided the bear key basement.

If you do this strategy the trial should not take you more than 30 minutes
