Challenge Rooms

Good rooms, meh rooms, rooms that really suck

[1] Fate's Beginning
Trade your Duty Badge for a Puzzle Cube at the Room 1 Teleport Master
Use the Forge beside him to repair, buy potions, and exchange Mirage Celestones for Dice Tickets
Choose 'Start the Challenge' to exchange your Puzzle Cube and 1 Dice Ticket, for a random die (1-6)
Right click on the die, and you'll move forward that many rooms i.e. if you get a 5 die and you're in room 1, you'll end up in room 6

[2] Chest of Mystery
Open 5 chests for quest items, get a die.

[3] Slaughterhouse
Kill 5 monsters, get a die.

[4] Mice Bashing
Kill 10 monsters, 1 hit each, use auto attack, get a die.

[5] Count the Apples
Count either the red, white, or blue wisps. Choose correctly, get a die.

[6] Open Sesame
Kill the boss mob in this room, who does a very weak AOE dmg (~100 every few seconds)
When he dies a Teleport Master will spawn, talk to him to get a die
The boss will respawn in about 20 Perfect World Goldseconds, so make it fast and don't AFK on auto attack for too long

[7] Have a Listen
Talk to the butterfly NPC to start the challenge
The goal is to find out which monsters have sound effects, the ones with the fire noise will 1 hit kill you, so slowly approach them until you find the monsters with no sound, and run through them to the other side
Try the 2 mobs against the left hand wall

[8] Try Your Luck
Costs 100k, open 10 chests and receive either a Perfect World Gold Sadness Card (sells for 1 coin), or a Ecstasy Card (sells for 1,000,000 coins)

[9] 100 Second Stand
Stay alive for 100 seconds
The mob in the center does AOE dmg, while the moving mobs do weak physical
Run to the corner of the room and kill any monsters that follow you, then just tank the AOE dmg
