Selecting drop item class in 3 has not been implemented into the game so you will not be able to select it.
Currently , item class A is automatically selected upon selecting the monster.

Click the Mission you want to complete to finish the dungeon in 4. Either just Hunt Boss/Hunt all the mobs including Boss.

Setting In&Out Number is for the number of times you'd like to be able to reuse the dungeon. You can just put this at the max 50.

Money, its the sum you pay for making the ucd and you'll have to pay it everytime you wanna use it too.

Click Create.

Play a UCD

Talk with UCD npc "Aco A" and select "Do you want to view UCD list?"

Select the dungeon that you want to enter from the list and press the "Enter" button on the lower right-hand corner.
Remember that you will have to have the entrance fee money to enter!

After 10 seconds on queue you'll be teleported into the dungeon.
If you're the party leader.then the members of your party also follow you into the dungeon.

When you complete the mission you'll automatically be teleported back to Aco A after 1 minute.

TIPs:
-TIME LIMIT...either 45mins/1 hour...Don't sit to much/AFK in there.
-The traps in the first map r easy too avoid, but all traps do little damage. Priests I know can have problems with Quest dungeon traps, not sure about UCD though.
-A warrior at 5 lvls lower then the mobs lvl in UCD can solo the dungeon of everything except the Boss.
-UCD mobs are easy...even for mages. Check my UCD dungeonat the forums UCD section for my experiences in there.
-DROPs
---the drops are always higher lvl drops, 1st had 20 above i think and 2nd has 28 above.
---First dungeon gives more drops then second.
---Accesories drop in these dungeons too, like the caramel wings in second.
---You can get rich on a couple of trips into first...just remember to sell to players first.
---You can also get all your gear in these dungeons.
---The drops are NOT monster specific in UCD...so make sure to get the most out of a trip by killing all the mobs.
-Leaving the dungeon
---You can wait for the time limit to end...you'll be next to the UCD.
---You can use your "pendant of memory" to teleport back to your respawn spot.
---You can hit O key and click Escape, then either wait the 5 mins or Click Character Selection and reenter the game, you'll be at luna/ your respawn spot.
-Leveling in UCD
---19-20 on main in 3 trips, get all your gear and a bigger wallet.
---Always nice to finish a lvl in UCD...
---Don't over do it...hit the mobs outside as well, they have some different non UCD drops too.
