MapleStory Classic World is expanding with Forgotten Hollow, a new area featuring unfamiliar monsters, exclusive quests, and a challenging boss encounter. The region gives players another place to explore as they progress through the midgame, offering new objectives beyond ordinary monster hunting.

Whether you want to level up, collect quest materials, or prepare for a new boss, knowing what Forgotten Hollow offers can help you plan ahead. Here is what players need to know about its level requirements, monsters, quests, rewards, and available facilities.

When Is Forgotten Hollow Coming to MapleStory Classic World?

Forgotten Hollow was not available at the game’s October 21, 2026, launch. It was planned as part of a subsequent content update, with November 2026 reported as the expected release window.

The final release date and content details should be checked against official announcements. Pre-release information provides a useful overview, but some requirements, rewards, and monster statistics may change before the area becomes available.

Forgotten Hollow Level Requirements

Forgotten Hollow is designed primarily for mid-level characters. Its regular monsters cover a range of levels, allowing players to progress deeper into the region as their characters become stronger.

Content	Level
Initial quests	39
Early monster hunting	39–45
Mid-level quest progression	45–50
Deeper cave monsters	50–59
Rotten Mushmom boss	60

These figures come from pre-release information and should be treated as provisional until confirmed in the live game.

If your character is approaching Level 39, start preparing by upgrading your weapon, checking your armor, and stocking up on healing items. Keep enough MS Classic World Mesos available for potions and equipment improvements so you can focus on exploring rather than repeatedly returning to town.

What Is Forgotten Hollow?

Forgotten Hollow is a new cave region connected to the forests around Ellinia. Unlike familiar hunting maps, it introduces a dedicated settlement, new monsters, and several questlines that encourage players to explore different parts of the area.

The region is planned to include ten regular monster types, a new boss, a fairy settlement, specialty shops, storage facilities, and an Arcane Station associated with Arcforge crafting.

These features make Forgotten Hollow more than a place to grind EXP. Players can complete quests, collect monster drops, interact with new NPCs, and work toward rewards as they progress through the cave.

All New Monsters in Forgotten Hollow

The planned monster roster contains ten regular enemies ranging from Level 39 to Level 59. Their different levels provide a natural progression through the region.

Monster	Level
Glowshroom	39
Raffle	40
Golden Stirge	42
Aqumander	43
Echopus	45
Rafflesia	47
Duskmander	50
Myewood	54
Rotten Mushroom	56
Sporewood	59

Several monsters are also connected to specific quest objectives. Glowshrooms, for example, are associated with map fragments, while other creatures provide materials needed by NPCs.

Before choosing a farming location, check your active quests and identify which items you need. Hunting the right monsters can help you earn EXP and complete objectives at the same time.

Rotten Mushmom: The New Forgotten Hollow Boss

Rotten Mushmom is the main boss planned for Forgotten Hollow. Pre-release data lists it at Level 60 with 86,400 HP, making it considerably tougher than the area’s regular monsters.

Its high HP regeneration is an important part of the encounter. Test information lists regeneration of 864 HP per tick, so players may struggle if they cannot maintain consistent damage.

Fire and Holy attacks are listed as effective options in the available test data. However, these details may change before release, so players should verify the boss’s final stats and mechanics before settling on a strategy.

Preparation is particularly important for characters attempting the fight around Level 60. Bring enough healing items, make sure your equipment is suitable, and consider forming a party if your damage or survivability is insufficient.

Forgotten Hollow Quests and Rewards

Forgotten Hollow introduces several questlines that connect the new region to Ellinia. These missions involve collecting materials, defeating monsters, and learning more about the cave’s inhabitants.

Grendel the Really Old’s Questline

The introductory story begins with Grendel the Really Old in Ellinia’s Magic Library. Early objectives involve collecting materials from familiar monsters before directing players toward Forgotten Hollow.

Completing the opening quests introduces the region and leads players to the characters living inside the cave.

Zelya’s Questline

Zelya can be found in the Cave Fairy Sanctuary. Her quests involve collecting map fragments from Glowshrooms and gathering materials from other monsters in the region.

As the questline progresses, players encounter additional objectives involving Aqumanders, Echopuses, and other creatures.

Nyroth’s Questline

Nyroth provides further objectives inside Forgotten Hollow. These quests involve collecting items, assisting other characters, and exploring the deeper parts of the region.

Myra and Daniel’s Quests

Additional quests become available as characters reach the required levels. Myra’s storyline explores the history of the cave’s inhabitants, while Daniel’s objectives involve collecting materials and defeating monsters in more dangerous areas.

Pre-release quest information lists rewards such as EXP, mesos, potions, return scrolls, and equipment scrolls. The exact rewards and requirements should be checked in the live game.

Forgotten Hollow Town and Facilities

The new region includes a central settlement where players can prepare for their next hunting session. Instead of returning to Ellinia whenever they need supplies or storage, they can use the facilities available inside Forgotten Hollow.

Two important locations are planned for the settlement:

• Cave Fairy Sanctuary: Home to NPCs including Zelya and Myen, with quests connected to the region’s story.
• Cave Fairy Department Store: Contains Luma’s shop and the Cave Fairy’s Storage.

Nyroth is also associated with an Arcane Station connected to Arcforge crafting. Together, these facilities make the settlement useful for both quest progression and inventory management.

The planned shop inventory includes healing potions, mana potions, food, arrows, throwing stars, and return scrolls. Having these supplies nearby should make extended hunting sessions more convenient.

How to Prepare for Forgotten Hollow

Before entering the new region, take a few minutes to prepare your character.

Reach the recommended level. Aim for Level 39 before starting the initial quests. If you are still below that threshold, continue leveling in areas suited to your character.

Upgrade your equipment. A stronger weapon helps you defeat monsters faster, while suitable armor can reduce your potion consumption.

Bring enough consumables. Stock up on healing and mana potions before exploring. Running out of supplies can interrupt your progress, especially when traveling through unfamiliar maps.

Save useful monster drops. Some quests require specific materials. Check your quest descriptions before selling or discarding items you might need later.

Manage your currency. Keep some mesos available for supplies and necessary upgrades. If you are considering whether to buy GMSCW Mesos, first assess your current funds, equipment, and progression goals. Avoid spending more than you need on temporary upgrades when the new area may introduce additional equipment and supply requirements.

Check the final update details. Confirm the release date, quest conditions, and monster stats through official game announcements once the update is available.
