Hypersmurf said:That's how armor spikes worked in 3E, but not shield spikes.
Y'see, you don't need spikes to add weapon enhancements to a shield. But you do pay for different enhancements separately.
To add a +1 enhancement bonus to a shield's armor bonus (or shield bonus in 3.5) costs 1000gp, and the shield must be a masterwork shield (150gp on top of the base price). To add a +1 enhancement bonus to a shield's attack and damage rolls costs 2000gp, and the shield must be a masterwork weapon (300gp on top of base price).
A +5 Shield of Heavy Fortification which is also a +5 Ghost Touch Flaming Burst weapon with the Throwing and Returning abilities costs 10gp (base) + 150gp (masterwork shield) + 100,000gp (+10 shield MPM) + 300gp (masterwork weapon) + 200,000gp (+10 weapon MPM), for 300,460gp total, and acts as a +5 martial bludgeoning weapon.
If you build it with spikes, it's a spiked shield, that acts as a +5 martial piercing weapon. You don't add any special abilities to the spikes; you add them to the spiked shield.
In 3E, and in 3.5.
Armor spikes in 3E were treated as a separate item. In 3.5, I'm not certain yet... "spiked armor" is an entry on the weapons table, not "armor spikes". I'd need to look into it more closely.

Hyp., I think on the fundamental question - the defensive and offensive capabilities of armour and shield are treated separately for the purposes of enhancements (mundane and magical) - we are in violent agreement, although you have undoubtedly put it into the technically correct formula.
Here's an interesting one, tho' - is my adamantine shield an adamantine weapon for the purposes of overcoming DR/adamantine or hardness? If so, how much should it cost, seeing as I gain both the benefits of being an adamantine shield and adamantine weapon.
[I note the SRD says that "only weapons, armour and shields normally made of metal can be made of adamantine", but then does not provide costing or DR values for shields made of the stuff...].
