Can I upgrade a masterwork set of armor or one made from a special material into a specific magic weapon as long as they're the same type? For example, can I take dragon hide leather armor and upgrade it into Milanite Armor with the dragonhide abilities?
Can I upgrade a masterwork weapon or one made from a special material into a specific magic weapon as long as they're the same type? For example, can I take a Fire-Forged Steel Morningstar and upgrade it into Enduring Bloom?
Tangential, can I upgrade a magical armor/weapon into their specific counterparts? For example, +1 dragonhide leather of fire resistance into Milanite armor or a +1 fire-forged steel morningstar of igniting into Enduring Bloom?
I'll just leave this here.
