Sunjang District Mission Henchable? *spoilers*

I'm trying to do the "Sunjang District" mission where you must kill Shiro's spiritual form. Is it possible to hench considering you can't make the henches pick up the urn or the spear? Thanks in advance for whatever help you can offer.

Alright, I answered my own question. If you are henching it, my best advice to you is to bring neither of them. Also against the Constructs, it is nice to have a ward for your casters to hide in, so bring the earth henchie. Go in a counter clockwise direction around him. Its easier. If you want, someone could close this forum.
