Thralls are a shield to their attached Magos. Can't fight at all, but they can shield. They cannot be buffed to fight better, because feedback kills ~70% of the unit
However, a Magos cannot score an objective if the unit is ever engaged in melee, and he's the only source of damage. Furthermore, he cannot explode the unit by himself because only Archimandrites can cast two powers in the same turn, so he has to recruit another guy

I'm just saying, Thralls don't convince me
