It used to stand on the Core and let anyone walk up. Now it growls at anything inside 4.5 m and bites inside 2.6 m — one bite concusses, a second in the same window kills, and carrying the Core off still gets you killed outright.
It guards the Core wherever the Core is lying — in its cradle or in a cart.
Hit it and you become its problem. It drops whatever it was doing and comes for you, and a wrench no longer interrupts its lunge.
Guarding and grudge work by scent and touch rather than by sound and light — a wall still stops it, but standing silent next to the Core will not save you.
With prey in its jaws it defends the spot where it stopped instead of chasing across the level.
And it stops turning up too early
The Hound no longer appears while the Core is still sitting in its cradle — its entrance is held until someone first lifts the Core. A live Hound does not hear a cradled Core and will not walk to it.
