Do people use them?
I guess you can reach a point where shard of power are not really required. I know to create the stable undead you need this so its something to add.
I am completely unsure about what the unstable do.
They all seen to get crushed by anything stronger than a gust of wind.
More fluff. I created a few and the green dragon wandered down and killed them. Skinny Bob, my only one left, just hangs out around the base, but I wouldnt count on them as any viable defense against raiders or the Pruge.
I’ll stick with scorpions.
Those will knock down any human raiders that come to my base.
Those are worth the Demon blood I feed them.
