Warforged & Natural Weapons

[SorO_Lost]

I thought of a silly trick that I'd like to check the validity on.

Section 1 (unarmed as a true natural weapon?)

(click to show/hide)

Battlefist (eberron campaign setting)
An Attached Warforged Component. This noted as a +1 weapon that covers your hand (like as spiked gauntlet) and improves Slam/Unarmed Damage, in addition the Enchantment Bonus(es) is carried over to Unarmed Attack/Damage.

Graft Weapon (fiend folio)
Makes any manufactured weapon a Natural Weapon by replacing your hand with it. Gives a +1 Competence to Attack/Damage rolls & -2 penalty to any Skill/Ability Check requiring the usage of (both?) hands, like Disable Device.

So we Graft the Battlefist to our hand. Lo and behold, we have Unarmed Strike as a Natural Weapon rather than being treated as one for various effects. Which means like any other Natural Weapon we can toss it on after a Manufactured Full-Attack routine. However in this strange case everything is named "Unarmed Attack". IE a Monk with BAB of +6 gets two normal attacks which will be the standard Unarmed Strike plus his Natural Weapons which will be this Grafted Unarmed Strike.

Section 2 (slam attack fun)

Slam Attacks
Per intent on the wonky Natural Weapon rules, this attack seems to use both your hands which prevents usage of any Manufactured weapon in your hand. So no go on Slam unless...

Large Size
If you are Large or bigger you can make a Slam Attack with each arm (link).

So this gives us two Slam attacks and more importantly the excuse to say a "Slam" consumes "one hand". Meaning that you can use your Slam attack with your right hand, Grafted Battlefist in your left hand, and Unarmed Strike with your feet or whatever.

Section 3 (augmentation)

(click to show/hide)

Second Slam (races of eberron)
Is a direct exception that adds a second Slam Attack so long as you Full-Attack and use your Slam once. As the above, we're using one Slam even through we could make two, this exception applies and adds another attack at the price of a single Feat.

Necklace of Natural Weapons (savage species)
You can enchant the Battlefist with a Holy, as it notes it adds extra damage to your weapon and Battlefist doesn't actually deal damage but instead transfers it's bonuses to your Slam/Unarmed weapon(s). Now we buy a +1 Collision Necklace of Natural Weapons for the standard Unarmed Attack, there again transference.

Scorpion Kama (magic item compendium)
And finally, Scorpion Kama. It's a Kama that deals your Unarmed Damage which would include Holy/Collision, but also it add it's own bonuses. Let's just add Blurstrike. So for the price of a +2, +2, and +1 addition which costs 18,000gp we've created an effective +5 weapon. A 32,000 gold cost reduction if you don't factor the raw price of the Kama. Which I think is somewhere around 6k total, so you still save money. Obviously, this lets you afford more Enchantments for the same price.

Cave of Gems (mysteries of moonsea)
Really just a minor bonus. Put a Masterwork weapon near a crystal and it gains a certain Enhancement, for a flat rate 2,000 gold. As a +1 weapon, the Battlefist must be inherently Masterwork. So ransack the area and tack on Flaming, Frost, and Shock for 6,000 gold before you use Graft Weapon.

Section 4 (all works out)

(click to show/hide)

Assuming each part is accurate. It kind of works out to
Effective +5 Scorpion Kama: 56,302gp (+1 & 6,302gp base).
Effective +5 Necklace: 50,900gp (900gp base).
Effective +5 Battlefist: 50,600gp (+1 & 2,600gp base).
Graft Weapon: 1,000gp.
Cave of Gems: 6,000gp (2,000gp per, used all three).
----------------------------------------------------------------------
Total: 164,802gp.
It's an 80% increase in bonuses as a single effective +10 weapon costs over 200,300gp, and you still have 35,498gp left over to spend.

As your Full-Attack you make as many Unarmed Attacks as normal, plus one Natural Unarmed Strike all of which benefiting form this Enchantment stuff. Then finally you make two Slam Attacks. And maybe a Snap Kick or something if you really want more

Let me know if I missed something or if it sounds A-OK rule wise to you.

As to section 2, you only get one slam per limb, though assumed to be arms. Unfortunately much like the monk's unarmed attack (and not just the feat) this is not always true. Some critters slam with odd appendages.

As to your result (4), as long as you aren't stacking enhancement bonus' it seems fine. Though you have eaten a throat slot and possibly the hands. Can't remember if components take slots or not. Nice trick
