How to get additional Hellcannons as Archaon?

[The Quban]

While playing my first campaign as Archaon, I can't seem to figure out how to get additional gifted Hellcannons for my other armies. Any hints how to get this particular gifted unit to unlock more than once?

You need to get them from your gifted recruitment, to have more to recruit you have to have the applicable gift of chaos unlocked, to unlock that gift you need to spend/sacrifice souls to undivided causes.

There are some events that may give you the chance to get a few or reduce the initial cost of the gift.
