Made of overlapping, lustrous black scales of standard-grade adamantine, this +2 greater resilient Fortification adamantine scale mail seems to momentarily thicken at the point of impact when hit.
Whenever the armor's fortification rune successfully turns a significant foe's critical hit into a normal hit, one of the scales on the armor turns violet. You gain resistance to physical damage equal to the number of violet scales, to a maximum of 8.
At dawn each day, all the violet scales return to normal.
Craft Requirements The initial raw materials must include 1,600 gp of adamantine.
Effect: Impenetrable Scale
Traits
A character can invest only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
