The Dragoncave is a chamber on the east side of the Underground Jungle.
The entrance is located in the extremely dense rock wall and is blocked by a large rock.
Inside the chamber is a large, egg-shaped rock structure on the ground, from which the boss Suomuhauki will spawn with an Earthquake-like visual effect (without falling debris) when approaching the center of the egg after digging out parts of it.
Killing the boss Rewards a Max health upgrade and a powerful Wand.
The Dragoncave, including the boss, also appears in Parallel Worlds.
