Daily Limit 3 entries per day. Dream Defender is closed at the last 30 minutes of Sunday to the first 30 minutes of Monday, so take note if you wish to perform the quest near reset time.

In Dream Defender, you have to destroy purple (bad) music boxes to turn them yellow (good). Monsters will however seep in to attack the yellow music boxes to turn them purple. The goal is to maintain more yellow music boxes than purple music boxes (note, it is different from having 5 yellow music boxes) in 3 minutes. If there are more purple music boxes than yellow, the bar will become more purple; if the reverse is true, it will become more yellow. In general, it is somewhat related to Mu Lung Dojo. 1 Dojo floor cleared = about 1~1.3 Dream Defender stage (not applicable if cleared floor 41 in dojo)
 * The number matters: if there is a significant difference, the bar will move more; if there is a small difference (3 vs 2), the bar will barely move (but over time it is visible)
 * 5 purple box, 0 yellow box: bar shifts by 7.5% towards purple every second
 * 4 purple box, 1 yellow box: bar shifts by 4.5% towards purple every second
 * 3 purple box, 2 yellow box: bar shifts by 1.5% towards purple every second
 * 2 purple box, 3 yellow box: bar shifts by 1.5% towards yellow every second
 * 1 purple box, 4 yellow box: bar shifts by 4.5% towards yellow every second
 * 0 purple box, 5 yellow box: bar shifts by 7.5% towards yellow every second
 * Every stage starts with 50% yellow 50% purple bar, with 3 purple music boxes and 2 yellow music boxes.
 * Tactic board shows the map layout, you will start from the middle.
 * Purple square indicates purple box at that area, you should tend to that area.
 * Yellow square indicates yellow box at that area, you can ignore that area for awhile.
 * If it is blinking and it is originally yellow, means it is turning purple, prepare to rush there.
 * If it is blinking and it is originally purple, means it is turning yellow, keep hitting.
 * Every stage cleared gives Dream Points (current stage number cleared, rounded down to nearest tens) that you can use to help yourself in later stages. Dream Points are stored forever in your character (max 3,000 Dream Points can be stored)
 * There is an unlimited number of stages, each stage will increase the HP of music boxes and monsters.
 * You failed the stage if either of these 2 situation happens:
 * Reached 3 minutes time limit but the bar is still not fully yellow
 * Bar is fully purple
 * Every 10 stage is a checkpoint, if you cleared that stage you can start from there directly (however if you started from there and you failed straight away, you get no rewards)
 * Starting from 30 stage, every 10 stage you can claim a useless medal for achievement purposes.
 * Ranking is based on depth (stages), then speed (time taken for the last stage)
 * Top 5 Dream Defender ranking will be displayed as NPCs in Lachelein (left of clocktower), when you entered Dream Defender 3 times for the day you can go to each one and get Dream Coins. (24~36 Dream Coins in total) Distribution as follows:
 * 1st place: 10~14 Dream Coins + Effort bonus Dream Coins
 * 2nd, 3rd place: 5~7 Dream Coins
 * 4th, 5th place: 2~4 Dream Coins

Rewards
 * 1 Dream coin every 1 stage cleared, if you started from checkpoint it assumes you cleared all the stages before the checkpoint (assuming you cleared at least 1 stage when you entered from the checkpoint). 30 Dream Coins = 1 Arcane Symbol: Lachelein
 * 3,634,300 EXP + 363,430 EXP every 1 stage cleared, if you started from checkpoint it assumes you cleared all the stages before the checkpoint (assuming you cleared at least 1 stage when you entered from the checkpoint).

Based on your Arcane River progress, you can choose to skip rounds to receive Arcane Symbols instantly and use up 1 clear count, based on the best result of the day (EXP is not given). You can still choose to perform it normally if you wish.

If you tried your best and you still could not perform well, you can obtain bonus Dream Coins from the 1st place player NPC. Effort bonus is applied per entry and stacks, excluding auto-clears. (Example: Manually clearing Stage 3 for all 3 entries without using auto clear lets you get 5 ×3 entries = 15 coins as effort bonus.)

 * Stage 2: -4 Defense (-20%)
 * Stage 3: -6 Defense (-30%)
 * Stage 4: -8 Defense (-40%)
 * Stage 5: -10 Defense (-50%, means if you touch the Toxic spirit when it is the biggest twice in the same round, you will definitely get kicked out)
 * If you have 6/20 Defense or less (30% or less), the defense bar will start blinking.
