Hi,

I was looking at the Iron Warriors entry and I noticed that Warsmiths can take a Cortex Controller. On page 89 of Extermination the entry for Cortex Controllers state that any Forge lord can purchase one. Then it states "If at least 1 so model equiped is present in the army then a castellax ..."

This presents a slight confusion to me, do this mean the rules specifically state that only a forge lord can take the castellax as an optional Heavy? or does this mean any model equipped with a Cortex Controller can take the optional Heavy?

I have trawled forums and have found nothing to say either way.
