Need Monster Like This Image

[Lvl 12 Procrastinator]

I would like to create a CR 12-13 encounter involving the monsters from this image. (Source unknown)

In my setting these creatures roam the blasted landscape of a hellworld collecting the unfortunate souls who find themselves magically transported there.

I was thinking about starting with Retriever as a base and making modifications from there, but I was wondering if maybe someone here might have a better idea.

Cheers!

Try the bleeding horror template. It's absolute nightmare fuel and they can summon a tornado of blood. I used it and some size modifications to turn a platypus into a deadly encounter for a 7th level party.

Hrmm... Well using the human in the picture as scale that looks to be around the Gargantuan-Colossal mark for size.

So my suggestion would be a Desecrated Necrocraft creature.
They are basically animated objects fueled by necromancy.
The options provided are morphic so you could have a variety of types of corpse horrors.

Thing is that this would mean you'd have to level the monster up yourself as the Necrocraft doesn't have examples provided for larger creatures.
Wouldn't be hard to just use the Stat scores on the Animated object chart though.

Neat! Never seen Neocraft before. Interesting.
