Creating Power Stones

[CheshireCatAW]

So, planning to make a Power Stone with a level 1 power and my manifester level as 1. According to the SRD the formula for cost is 12.5 x 1 x 1. I have to pay 1/25th of this as xp.

Is there are hard-and-fast ruling as to how this works out? Do I pay a minimum of 1xp for any Power Stone I empower? Do I pay 1xp for every two? Do I pay NO xp for level 1 powers?

Thank you.

No - you pay 1/25th of the base price as XP, not the crafting price. So, for a 1st-level power stone, you pay 1/25th of the 25gp base price, for exactly 1 XP.

You can look at the scroll creation costs, since they're what power stones are equivalent to. Scrolls, unlike power stones, have 0-level versions, and they do in fact still cost 1 XP to craft.

I figured I was missing something.

Thank you very much.
