The Crypt of Illusions is a high level, special timed hunting zone for characters Lv. 84 or higher. This enigmatic dungeon exists between reality and dream, where the laws of nature bend to the will of ancient magic. Entry to the Crypt is time-limited, and can be accessed through the Special Hunting Zones window.

Players can prolong their time in the instance by purchasing a Crypt of Illusions Extension Stone from the L2 Coin shop or by looting them from monsters. The Crypt of Illusions is available 20 hours per week, with the possibility to extend access up to 154 hours through special means.

The Four Seals

The zone is split into four quadrants (Seals), each with their own unique properties and Seal Stones. These mystical barriers must be navigated strategically, as each Seal presents different challenges and rewards.

Each quadrant represents a different Seal, with unique monster types, weaknesses, and strengths:

	Seal of Gnosis (Dusk)	Red Seal Stone (Lilim)	Weak against Melee Strong against Bows
	Seal of Avarice (Dusk)	Yellow Seal Stone (Lith)	Weak against Magic Strong against Bows
	Seal of Strife (Dawn)	Blue Seal Stone (Nephilim)	Weak against Magic Strong against Melee
	Seal of Avarice (Dawn)	Green Seal Stone (Gigant)	Weak against Bows Strong against Melee

Special Raid Bosses

A special raid boss will spawn depending on how many monsters are slain from each faction:

• Dusk monsters will summon Spirit of Lilith
• Dawn monsters will summon Spirit of Anakim

Forgotten Manuscripts

The Seal Stones collected from monsters can be exchanged with Illusion Explorer Akirus near the entrance for Forgotten Codex. These codexes are essential for learning powerful end-game skills.
