Labyrinth of the Poison Dragon

Labyrinth of the Poison Dragon (毒竜の迷宮, alt. Maze of the Poison Dragon) is a dungeon on the 1st layer. This dungeon was shortened and included in Episode 01 of the anime.

Introductory Arc
After Maple played NewWorld Online for a couple of days, she began to notice the players around her weren't in their starting gear. When a great shield caught her eye, Maple called out to the wearer, and was told about crafting and introduced to a crafter. Because Maple was a beginner, the great shielder Chrome and the crafter Iz added her as a friend and told her about the Labyrinth of the Poison Dragon in good faith. They couldn't have foreseen Maple would casually stroll into the dungeon shortly after only buying some potions.

After Maple entered the dungeon alone, She found it difficult to kill monsters. Her progress accelerated after she learned the Shield Attack skill by trying out various attacking methods.

A while later, Maple entered the boss room. Because she knew the dungeon was poison focused, she had hope she could survive its attacks and poison. She used Meditation and timed her potion usage well, hoping she could acquire an immunity to poison. After she exhausted her potions, she gave up just before she acquired Poison Immunity. With a high VIT and an immunity to poison, she could no longer be defeated. After some troubleshooting, she discovered she could eat the hydra without it regenerating.

Before long, she defeated the boss. Along with it came the Hydra Eater skill and her Poison Immunity evolved into Hydra.

Guild Founding Arc
With Mai and Yui joining Maple Tree at such low levels, Maple was sent to power level them at the Labyrinth of the Poison Dragon. In order to keep Mai and Yui a secret from the other guilds, Maple was forced to maintain her Atrocity's demon form.

Because Maple found it boring to merely kill the boss over and over again, Maple and the twins decided to try and set a personal record on how fast the could defeat the boss. Before long, they were able to get the time below 2 minutes and 30 seconds, and the twins both learned Destroyer and Conqueror.

Rewards
When Maple defeated the boss on her first solo attempt, she received the following UNIQUE SERIES:
 * Destruction Growth : When the equipment would be destroyed, its benefits are not lost, its status benefits improve, and it is repaired.
 * Skill Slots : For every 15 levels of the wearer, the equipment with this skill gains an extra skill slot, with a minimum of 1 skill slot available (Lv30 2 slots, Lv45 3 slots, etc.). Skills that are put into skill slots are lost and cannot be reacquired. Skills that have a mana cost receive 5 free uses per day before requiring mana.
