Higher Caster Level Pricing?

[Barachiel Shina]

Ok, what if I need an item to have a higher caster level? Which would make it harder to dispel, for example, and have better saves, etc? What is the pricing formula for that?

In particular, I want to make an Amulet of Proof Against Detection and Location that is not CL 8th, but CL 15th. How would I determine what the price jump would be? I doubt the price stays at 35,000gp?

Check the CRB towards the end (start at the back). You are looking for crafting magic items. Alternatively, check here.

Now you should be able to get a feel for what sort of price jump to make when increasing the caster level. You will notice that under the "Spell Effect" section in "Table: Estimating Magic Item Gold Piece Values". Every single option is multiplied by the caster level (as well as spell level and some base cost). This implies that you should divide out the current caster level and then multiply in the new caster level.

15*(35,000 gp/8) = 65,265 gp

Also, whenever you are pricing custom magic items consider these words of wisdom from the same webpage linked above.

"Not all items adhere to these formulas. First and foremost, these few formulas aren't enough to truly gauge the exact differences between items. The price of a magic item may be modified based on its actual worth. The formulas only provide a starting point."

Thanks for that, I'll copy and paste this into my magic item notes to use as reference :D
