Buying larger than +8 stat magic items

[penbed400]

Hey everybody. I was just wondering how the money scale worked for doing that. Such as if you wanted to make a +10 gloves of dexterity then how does the money scale for buying one turn out. And for larger than that as well. I see that the scale for stat modifying items scales up a little bit for

+4 = 16,000gp
+6 = 36,000gp
+8 = 64,000gp
+10 = ?
+12 = ?
+14 = ?
+15 = ?


Is there a formula I'm not seeing here? How would you scale up prices?

[Mando Knight]

A +8 item is 10 times as much as you think it is, according to the SRD.

The formula you're missing is that it's the square of the bonus, times 1000. But as Mando Knight points out, if the bonus is greater than that available pre-epic, it's multiplied by 10. So, 1,000,000gp for a +10 item.

edit: Oh wait, +8 is itself epic... so where did you get that price for it?

[penbed400]

Oh well I just figured that a bracer of armor +8 would be equal to it, that is indeed my bad.

[Heliomance]

Nay. It goes like this for stat-boosting items:
+2=4,000
+4=16,000
+6=36,000
+8=640,000
+10=1,000,000
+12=1,440,000

And so on and so forth.

Quite the leap, there.

EDIT: In price, not in logic. Above poster is correct.

That's what you get for items which strain the credibility of reality to its breaking point, I suppose.

All the formulae for this are in the back of DMG, or in Magic Item Creation Guidelines. Stat boosters use the following formula:
"Bonus Squared * 1000gp"

Now, the one exception are Epic magic items: Epic Magic Item Creation Guidelines state that if an item exceeds the pre-epic maximum bonus (listed in the Epic Item Creation Guideline above), the item is Epic and costs 10 times its normal price. Note that this happens only if a bonus maximum is exceeded; an item that costs over 200k is also Epic, but if it's e.g. the consequence of adding too many +30000gp abilities to a single suit of armor (such as Greater Shadow, Greater Silent Moves, etc.), the cost does not increase. However, if the armor has base bonus of +6, the cost is much higher.
