We might also look to the demonflesh golem for inspiration...
A spell with the chaotic or evil descriptor (such as chaos hammer or unholy blight) breaks any slow effect on the golem and cures 1 point of damage for each 3 points of damage it would otherwise deal. It is fully affected by spells with the law or good descriptor, unless its construct traits make it immune to the spell's effects (it cannot be blinded by a holy aura, for example, because that effect allows a Fortitude save).
As an extraplanar creature, a demonflesh golem on the Material Plane can be driven back to its home plane by a dispel evil or dispel chaos spell (as well as by holy word or dictum), but it is not affected by banishment or dismissal since they are not good or lawful spells.
Speaking of extraplanar, I think this should have that subtype and hail from the Abyss. Thoughts?
