I had already asked sirp to fix the weapon spliting property. There was then a version that just granted one weapon to one natural weapon, which I aproved. It was then changed again, and for that and others disaproved.
What, exactly, is wrong about it as it is? You don't get to double up on anything, you just apply your weapon properties to all your attacks, just as you would if you were wielding a manufactured weapon and making all of your (iterative) attacks with that.
... wait, actually, never mind. I tend to think solely in quantities of attacks and forget about the other aspects of the attacks, like that iteratives are at -5 through -15, and come online later than the commensurate number of Scaleshift natural attacks, whereas the natural attacks are at a fixed -5 (and trivially -2 or even -0) and come online relatively early (I can't believe I never noticed just how early... and scaling up to 6 attacks!). I also tend to forget about Rapidstike (don't own nor have read Draconomicon), effective immunity to disarm and sunder (I can count on one hand the number of times I've seen those options do anything other than waste an attack, but it's still a thing), and that funky interaction with Monk's Unarmed Strike (to add manufactured attacks in your natural attack routine). So, yeah, I see where you're going with this and I agree, it needs a change.
Besides full items all the time, multiplying weapon enanchments by 5 while make them immune to disarm, sunder and dispel (clause on the class is irrelevant because the item is melded and thus will never be a valid target for dispel magic). I also don't remember Dual Ideal at 8th level from the previous version.
They should still be valid targets for dispel -- suggestions on how to word a clarification? And Dual Ideal was always at lvl 8 for the class.
Note that using the weapon enchantment thing means that the natural weapons can be sundered...
What's the HP of a dragon's claw/wing/bite again? Does any DR you have applies to it? Does the main body takes damage? Can't you just transform again to get it back? This is all lots of extra work for my part.
The first part is easy however. Just state they can now be dispelled as if they were worn magic items.
It doesn't. The current version can't be disarmed or sundered, just like normal natural weapons (it's just manufactured for interacting with weapon properties, mostly so that you can't double dip with a Necklace of Natural Attacks).
As for dispelling, it says that already.
When a scaleshaper scaleshifts, any equipment he wears other than armor and held objects shifts with him, altering its form to accommodate the new shape. Objects that do not or cannot resize themselves meld into the new body, but retain their properties and can still be targeted and affected by spells and effects as though they were worn normally.
Edit: Hmm, technically not. That passage is only referring to non-armor, non-held items that meld. Good catch.
