The construct penetrated the outer layer at about 3:00 AM. It thoroughly destroyed it with its tendrils. I think the ordinary Operator Signs have worn off, as it is staring the manequin down while very close and intendedly. It has done so for almost an hour and a half now.
Final verdict: The Ichthus-Operator Sign Jakob uses as his avatar lasts as repellent for 28 hours, at the end of which I recommend having formulated an escape plan or have erected fresh ones, because the construct will be agitated and ready to tear things apart.
