[Sombre]

Same way he got the chains off the wall when he was imprisoned, he'll swing them around until things break.

Seriously though he has 3 attacks. Fleshflayer his magic weapon causes additional weakness and does 13 nostr damage, he then gets ogre smash str based attack and finally he gets a 'dark chains' attack which has secondaryeffect of enslave mind. I originally had the twin spear effect as a secondaryeffect so stuff he killed turned into soulless (and it worked, amazingly) but I decided that would be cooler in some other mod if a recruitable unit used it as a straight up weapon.

So in this case the slaves are just decorative. He does spawn and command lots of nice slave chaff though, which when it dies automatically becomes soulless.
