The master smiths of the Kakita family claim that they produce the finest blades in the Empire. A Kakita katana is made of exceptionally fine steel, durable and flexible, and is able to withstand the passage of a thousand years. The master smiths use only Hida steel in their blades, claiming that it far outshines any other in the Empire. A Kakita blade is distinguished by its light weight and flexibility, and by the fine lines of bluish damask running down the cutting edge, causing the entire blade to shine with a slight tint. These blades are usually bestowed only upon samurai who have proven their honor and courage, and only very rarely upon samurai who are not of the Crane clan. A non-magical Kakita katana has a natural +2 enhancement bonus.

Mined from secret locations in the Astral Plane, this malleable metal holds its shape only in the hands of a psionic being. When an item forged with ferroplasm is unattended or held by a non-psionic creature, it melts and temporarily loses all special powers. But when wielded by, psionic creature, such an item immediately springs back into its true shape and regains all abilities. In its proper form, a ferroplasm item glows with a violet light (illuminating a 10-foot-radius), unless the item’s owner mentally quenches it. In an area where psionic powers do not function, it collapses as if in the hands of a non-psionic creature. Ferroplasm adds to the quality of a weapon or suit of armor based on how much of the material is used. Thus, ferroplasm full plate offers greater protection (as well as a greater cost) than ferroplasm chainmail, and a ferroplasm greatsword offers greater offensive capability than a ferroplasm quarterstaff. Weapons fashioned from ferroplasm have a natural enhancement bonus to attack and damage. Armor fashioned from ferroplasm has a natural enhancement bonus to AC. These bonuses do not stack with other enhancement bonuses. Weapons or armor fashioned from ferroplasm are treated as masterwork items with regard to creation times, but the masterwork quality does not affect the enhancement bonus of weapons or the armor check penalty of armor. Ferroplasm has hardness 20 and 40 hit points per inch of thickness when in its true form, and a hardness of 5 and 10 hit points per inch of thickness when soft.

I think no, but Damned if I don't want to figure out how. It "seems" like it should. One is from masterwork high quality craftsmanship, the other is from the material's psionic properties. Thoughts?

They're both enhancement bonuses. Enhancement bonuses don't stack.

[NunoM]

They're both enhancement bonuses. Enhancement bonuses don't stack.

I second this.

Stretching a bit, maybe these kind of bonuses could have been classified as "circumstance bonuses", due to the "circumstance" of being constructed in a certain way or of a certain material; or maybe even given different types of bonuses like "craftsmanship" or "special material"... That way they would indeed stack. As they are, they don't.

EDIT: Maybe the designers did this to prevent the MW quality enhancement bonus (to attack) from stacking with magic weapon enhancement bonuses.

I third it.  To me, "natural" just means "non-magical", but it's still an enhancement bonus that doesn't stack with other enhancement bonuses.

[Gazzien]

In addition, there is only Higa Steel used in the katana, so you couldn't even make it out of ferroplasm.

Thanks. Was hoping.

Meanwhile, the fluff is rather interesting.


I haven't needed to check up on how OA gets to and from the Astral.  But supposing 9s are available, you know/infiltrated the Smiths of that family, got one(or more if necessary) out in the astral, didn't freak them out breaking out the Blinky non-honorable stuff.  Fusion power of course.  PAO on the fused item.  Make and pay for a +4 item.  Use a higher level spell/power to pull it all off, say a Bend Reality.  Strange Crafting while hanging out in the astral, is not non-dangerous.  Sounds like a decent adventure.

Sir your sword is glowing.
<whisper>  Cap'n, I failed my knowledge checks.  Better keep an eye on him.
