Nice to see that WOTC seems to be listening to customers and doing what it can to eliminate grindspace by decreasing monster hp and increasing monster damage (assuming this is indeed a trend).
Unfortunately their writing still treats words like play-doh that can be smushed into any shape desired and thrown against a wall until enough stick so that it looks kind of like art. For example, in the very short entry we have here, it says the pod demon is "disgusted." By what? I assume they meant "disgusting." Then there's that mixed metaphor about "under the heel" of the "Chained God." "Bound to the Chain God" wouldn't have worked? "Shackled"? And from a larger game-mechanics standpoint, "madness" or "demented" is mentioned in every paragraph of the flavor text, and seems to play a large role in the demon's place in the game world, but it has no representation at all in the mechanics or stats.
It does look like it would be a lot of fun to use in combat, though!
