Warpsmith

No, sir, totally not a Warsmith.

Warpsmiths are a new model of Chaos Space Marine introduced for 6th edition. Warpsmith's are Traitor Techmarines, allied with the Dark Mechanicus. Apparently, the difference between the Warpsmith and Techmarines is that while Techmarines revere technology, Warpsmiths subjugate it. Or something.

The difference between a Warpsmith and a Warsmith of the Iron Warriors is that the Warpsmith got augmentics because he worships the Omnissiah, the Warsmith got augmentics because he got a few mutations he didn't like.
