The creature I made is named Sorin Yeate. He is a half-orc with a major skin disease. As a result, he not only lives far from civilization, but he is also just dangerous to be near, as his condition gives off a poisonous and acidic mist of vapor. The properties of the mist can also be hallucinogenic. He uses this condition to protect himself. Unfortunately he is also deranged and will not listen to reason.
Sorin is a good creature to use if the PCs are in an isolated region. If they stumble on his lair, they will certainly smell an acrid stench if they get within 10 squares of him.
I would be interested if anyone has thoughts. I have attached a pdf of the creature. I have given him just the bare minimum to qualify as a Savage so that the features are clearly represented. This creature has a chance to hit the PCs fairly hard without taking all night.
Tactics are simple-spend your action points as quickly as possible and make as many attacks as possible in order to get the best use out of Savage. This should run really well against 5 Level 8 PCs; that would be the "sweet spot". Obviously, the higher the PC level, the easier it will become. This will be too easy for PCs over level 10.
Note-I have updated the pdf, and I also have a link to download the monster file, so you can easily put it in your games.
