Magic Item cost question

[Lord Stewpndous]

How much would Boots of Striding cost? Boots of Striding & Springing are 5500gp. Looking at the magic item cost table, it would seem that removing the +5 Jump bonus (5^2*100=2500) would reduce the cost to 2000gp for a speed increase of +10ft. What would it cost to increase the speed bonus to +20? 8000gp? What would a speed increase be equivalent to? a save bonus? an ability increase? Just curious because I want to put together a character with a ridiculous amount of movement as an experiment.

Any help is appreciated.

Thanks!

Your math looks quite reasonable; 2,000 gp for +10 ft. would translate to a cost of 2000 gp x (no. of 10 ft. increments)^2, for a cost of 8,000 gp for +20 ft. and 18,000 gp for +30 ft. This is consistent with the pricing scheme on weapons, etc., which is encouraging. I'd be sure to specify this increase as an enhancement bonus, to remain consistent with longstrider and expeditious retreat.

I don't know of any spells providing a base land speed greater than 60 ft., so I'd probably cap the effect at +30 ft.

First of all -- 5500 - 2500 = 3000 (Unless you are using the rule that an additional ability costs an addition 0.5% of the lesser cost.) :-)

I think that your assessment is fair. Bonus speed squared x 20 gives a pretty reasonable price. However, if you really are developing this as a magic item, I would make sure to put in a cap before it becomes 'epic' as well as a caster level cap for every +10 ft.

Good luck.

I kinda thought that formula worked but was concerned that instead of working like a actual bonus to saves or abilities that it is replicating a spell like longstrider for +10ft, which if you use the chart for a continuous spell effect the formula is: (spell level * caster level * 2000gp*spell duration multiplier)

So:
longstrider +10ft (1*1*2000*None b/c 1hr/lvl duration)=2000gp?
expeditious retreat +30ft (1*1*2000*2[spell has duration of 1min/lvl]=4000gp?

In this case for a +30 speed enhancement it would only cost 4000gp, but if we use the save/ability bonus formulas +30ft = 18,000gp

Which method seems more correct?

Thanks!

I would strongly recommend the one that Kirth and I suggested. Spells don't always equate well when giving fixed bonuses. Take a look at the spell "True Strike". There was an article on this on the WotC site a bit back. If you look at the rules for continuous spells, an item that gives +20 insight bonus to attack would only cost 2,000 gp.

Hi,
On a slightly different, but related point, I was wondering about the cost of Boots of Striding and Springing...
If you go by standard costings and build from scratch a combination of Boots of Elvenkind and Longstrider you get 2500gp (+5 acrobatics) plus (2000 x 1.5)=3000gp for the Longstrider. Total 5500gp which tallies with the book for Boots of S&S. However these non-standard boots give you an all round bonus to acrobatics, whereas the book boots only add to acrobatics (jump).
Should the book price of Boots of S&S be slightly cheaper?
