I was expecting Fire nail to be "Takes reduced damage from Immolators" or "Can not be set on fire"
Weaving Nail and Vampiric nail seem over powered. To take a hit from a Nightmare and completely reverse, potentially multiple times, could almost multiple how long a prop could survive, especially door cades
Sure I would like to see elemental nails and I would be fine with all of these being added assuming the two nails above are not added.
You could also have something like a "blast resistant" nail that would specifically take reduced damage from Bursters, Bonemeshs, Zombine nades, Bloated zombies. Plated nail may cover to much so if it was specific to melee attacks only then bam.
Another potentially overpowered nail idea is a nail that allows humans to phase through the prop faster
