Pricing an Altered Magic Item

[Stalker0]

First, I'm taking the horned helm from the Arms and Equipment guide and modifiying it. Normally it gives you a gore attack, and doubles your base speed. It takes a helmet slot, and costs 38,000 gp.

First of all, I just want the speed, not the gore, so how much would that knock off the price?

Second, what if I made it a boot slot? Helmets don't usually grant speed increases, so would the item be cheaper if I made them boosts? In other words, I want boots that double my base speed, and using this item as a guideline, how much should that cost?

My initial idea was 20,000 gp. That's 38,000 - 8000 (for the gore attack and the fact that 2 abilities on the same item costs more). so 30,000 / 1.5 (for the change in slot) = 20,000 gp.

I think this is reasonable with boots of speed, as those boots give a much better combat effect but this item does last all day.

Well, it's not 3.5e, nor is it strictly D&D, but in the 3.0e D&D Diablo II supplement (from WotC), an ability that gave +100% move speed, +2 dodge bonus to AC, and cannot be flat-footed (suffix: of Speed) was costed at 10,000gp. However, it's probably under-costed for standard D&D.
If you dropped the cannot be flat-footed from it, it'd probably be around 10,000gp in standard D&D. Could be less, depending on whether or not you subscribe to the MIC item pricing redesign.

any other insights?

In a boot slot I'd say 10k but only if it affected base speed only.

So a halfling monk20 would only get +20' out of it. Also I would make sure that you name the bonus, to avoid stacking silliness.

It's the doubling your speed that throws me off. That is a mechanic that went out of favor with the release of 3.5. Now, there is fixed pricing for +X ft. to your speed, but not for doubling your existing speed due to the problems with stacking and doubling.

"doubling one's base speed" is a wee bit of a no no balance wise.

It is much better to award a +X feet bonus to speed. Monks have ways of breaking such doublings in a hurry.

For +10 feet? I would cost it about 2000 gp

For +30 - 12000 gp, if it is on the appropriate body slot

Both of the above are "enhancement" bonuses as well. That means no stacking atop monk class ability.

Effectively, it's Boots of Permanent Expeditious Retreat, for purposes of pricing, yes?

Also, consider the following:

Horseshoes of Speed: These iron shoes come in sets of four like ordinary horseshoes. When affixed to an animal’s hooves, they increase the animal’s base land speed by 30 feet; this counts as an enhancement bonus. As with other effects that increase speed, jumping distances increase proportionally. All four shoes must be worn by the same animal for the magic to be effective.
