Dragonbone

Dense, resonant bone from powerful draconic creatures, valued for its durability and its ability to hold powerful enchantments.

Applicable items: Weapons, armor, shields, tools, rods, staves

Traits granted: Dragonbone

Effects: The item gains +1 Hardness, and if it has Durability, that increases by 50% (rounded up). Dragonbone weapons count as Dragonbone for weaknesses, resistances, immunities and special defenses, where relevant.

Scaling profile: Flat, with its own progression (below).

Scaling: Each time the item enters a higher item-level band, increase the Hardness bonus by 1 (to a maximum of +4) instead of increasing the Durability bonus further.

Crafting requirements: Boneworking or smithing tools, depending on the item, and properly prepared dragonbone.

Crafting modifiers: +50% raw material cost; Craft DC +2.

Restrictions: Rare and hard to shape: fine flexible garments, most bows and delicate clockwork usually can't be made from it.

Magic items: An especially stable vessel for magical crafting: if later made Masterwork or enchanted, it keeps the Dragonbone trait and its Hardness bonus.
