4. Season 21 Part 1-1 renewal

Entry level per floor

Every floor used to require level 770. Each floor now has its own entry level - the lower floors opened up, the top two moved higher.

Hunting ground Entry level before Entry level after
Deep Dungeon 1 770 730
Deep Dungeon 2 770 750
Deep Dungeon 3 770 770
Deep Dungeon 4 770 780
Deep Dungeon 5 770 780

Monster changes

  • Monster stats and the experience they give now scale to the character's entry level, rather than being fixed.
  • The hunting penalty inside Deep Dungeon was removed.
  • The debuff effects that Larva, Poison Bull Fighter and Thunder Lich applied to characters were removed.

Hunting penalty rule change

The renewal also changed how the hunting penalty works game-wide, and carved Deep Dungeon out of it.

Before After
No penalty applied if the character had not completed the 4th class change. The penalty applies in every class-change state (1st through 5th).
The penalty also applies when the monster level is 275 or higher.
Exception: Deep Dungeon floors 1-5 are excluded from the penalty entirely.

Monster levels can be checked in game under Knowledge Dictionary → Region / Monster.

5. What you go to Deep Dungeon for

The 4th class change quest

The 4th class change quest chain runs inside Deep Dungeon, against Sent, the guardian knight of Lugard.

Stage Objective Reward
4th class change (1) - Test of Qualification Sent appears in person and fights you. Reduce Sent's HP to 0, then talk to NPC Sent to complete it. 20 stat points
4th class change (2) - New Battle (1) Hunt 5 each of Deep Dungeon Skeleton Warrior, Deep Dungeon Cyclops and Deep Dungeon Ghost, and survive 5 minutes against monsters that keep spawning. If you do not get all 15 within the 5 minutes you can continue the quest - your kill count is kept. 30 stat points
4th class change (3) - New Battle (2) A second fight against Sent. This time he uses extra skills and casts far more often. Reduce his HP to 0 and talk to him to finish. -
