Gduar

Gduar was an aberration in the Upperdark, resembling a treant made of fungi. It mostly kept to itself, tending to its fungal garden. Amongst its possessions, it held the Third Imaskarcana.

Description
Gduar was a translucent mass, covered in mold.

Abilities
Though similar to a treant, Gduar had a number of abilities that set it apart from plants. It had a corrosive breath weapon, the ability to engulf enemies, and a paralyzing digestive acid which acted on anyone it struck or engulfed. Since its shape was less defined, it could not be flanked. It could animate fungi instead of trees.

Gduar's Garden
Gduar's Garden was in the northern reaches of the Darklands, beneath the Chondalwood. It was a small cavern where the creature cultivated fungi, often sending animate monsters to acquire live prey for it. The fungi in the zone made for a beautiful display, with glowing fungal caps, and a bioluminescent haze of digestive spores. Anyone in the area with those spores would be slowly killed by them.

Amongst other monsters, there were gelatinous cubes, shambling mounds, tendriculos, and a gray ooze. Gduar kept a small amount of loot, including the Third Imaskarcana. The deepest part of its lair overlapped with a powerful earth node.
