Constructs would be made using materials and the meterials would be lost. They would require High MD to get to move to the area you want them in, and would only combat defensively(if engaged)

Golems, classically a holy magic construct,
Would have the concioiusness of the activating mage transfered into it.

The Golem mage would loose spirit while possessing the golem, up to and including death.

If the golem is destroyed, the golem mage gets severe internal bleeding and stuns.

Differences-
Risen are "souls" and made from organic material.
Constructs are "elementals"(boggles) and are non organic material.
Golems are "mages"(pc) and usually carved from stone.

If there were no cost or sacrifice involved, there wouldn't be any benefits worth learning, and the entire system would be pointless. --GM Wythor
