But aren't techpriests always armed or accompanied by servitors quite capable of defending them after the first few rank ups? I just can't believe a fully fledged techpriest would go somewhere unprotected...
I've never read anything to that effect; especially in any of the RPG materials (though I haven't read everything pertaining to 40K.)
But really, it ultimately comes down to the GM's call.
