I used to use animated armor to do campaigns but now he has had cleave removed and assault . are there any Ironfist runes that still have the abilities cleave and or assault?
Not to my knowledge. Unfortunately the revamped paved over a lot of the more interesting Construct stuff
My recommendation is using poxbase.com to find which units have cleave and then grant it assault with the SL market, slum market.
Or you can use Zedin who has Cleave and cast Pride of Sarnghaver to give him Assault for a few turns.
