hound of tindalos looks like hound of tindalos (CleverRaven#74225)

I was testing some artifacts and after some FUN artifact effect I got to
see a hound duplicate, but hey look at that my tileset doesn't have a
sprite for the duplicate meaning the duplicate doesn't do `copy-from`

fix that I guess, it looks like all the important parts are overridden

When it moves, its twisted limbs duplicate, merge, disappear, and reform in dissonance, as if a hundred copies of itself were somehow forced to inhabit the same space. Extraneous to our reality, it moves between the corners of the world, hunting those that would dare step beyond time and space.",
