[RPG] What are the prices for Permanency when you don’t know the spell yourself

pathfinder-1epricingspells

I want to make an item, say a sword, permanently invisible and I am a little unsure as to the pricing required for this.

The price of the item doesn't need to be figured out.

Having an NPC cast a spell under the services rules is

Caster level × spell level × 10 gp

The price of a scroll is

Spell level × caster level × 25 gp

Now, invisibility is a 2nd level spell. If I was capable of casting the spell myself, odds are that it would be free. If I need a scroll for some reason then the price would be 2×3×25=150. From an NPC source it would be 3×2×10=60.

Permanency has some different requirements beyond just needing to be cast. In this case invisibility costs 5,000 gp in base resources. To obtain the scroll would be 5×9×25=1125, and the NPC 9×5×10=450.

The following prices do not include the cost of the item to make invisible.

To do the job yourself should be fairly straight forward and easier to manage (if not a bit more costly) at 150 scroll + 1125 scroll + 5000 materials = 6,250 gp.

To get the job done with an NPC would require a large city due to permanency being a 5th level spell. 60 for invisibility + 450 for permanency + 5000 for materials = 5,510 gp (a savings of 740 for some inconvenience).

Do I have the prices correct or have I missed any steps?

This looks almost correct. However, I'm almost certain a scroll of permanency must include as part of its creation (therefore adding to its price) expending material components equal to at least the amount it'd cost to have the the spell permanency affect whatever spell will be affected. In addition, the GM may require each scroll of permanency to specify the spell that permanency spell will make permanent.

Option 1: Use scrolls

Option 2: Use services

  • 1 casting of the 2nd-level spell invisibility by a level 3 caster (60 gp).
  • 1 casting of the 5th-level spell permanency on the spell invisibility by a level 10 caster plus material components (5,450 gp).

Option 3: Do it yourself

  • 1 casting of the 2nd-level spell invisibility at any caster level up to your own.
  • 1 casting of the 5th-level spell permanency on the spell invisibility at any caster level that's at least 10
  • Material components costing 5,000 gp for the spell permanency on the spell invisibility.

Option 1 costs a total of 6,400 gp. Option 2 ideally costs 5,510 gp. (I say ideally because were I a wizard who loves money I wouldn't cast permanency on some low-level punk wizard's invisibility spell; I'd make you pay for one of my far better solid, robust, dependable, level 10 invisibility spells. You don't want to skimp, do you? This will be permanent, after all.) (Tip: In the world of Pathfinder durations, permanent only means permanent until dispelled.) Option 3 costs only 5,000 gp, but you've to be an appropriate level 10 caster (necessary, in all cases, because of the minimum level needed to affect an invisibility spell with a permanency spell).
