Item Price Clarification

[CigarPete]

Wanted to price out an item and looking for clarification on where multipliers happen. Basically, I would like to buy Large Mithril Chain Shirt Barding for a Wolf Animal Companion

Large Barding x4
Mithril +1000gp (Includes MW)
Chain Shirt 100gp

If the Mithril cost is applied to the base price and multiplied , this is 4400gp and I am taking Mage Armor as a spell known and dealing with the occasional dispel risk.

If the Mithril cost is applied after the multiplier, the cost is only 1400.

What I would think, Mithril cost is added after the multiplier for barding, but before the multiplier for size, making the total 2400.

This really belongs in the Rules Questions section of the board as it is not specific to PFS.

[BigNorseWolf]

There's no RAW answer or clarification AfAIK.

I personally cannot see being charged more for the mithral just because its shaped like doggie armor rather than people armor.

[Thorkull]

Large size, however, requires more Mithral. That would make it reasonable to bump the price correspondingly.

[Katie Sommer]

No, but I can see being charged more for size large mithril armor than size medium.

Edit: meh, ninja'd

[Patrick Harris @ MU]

Special materials don't scale with size unless they say they do. Darkwood, for instance, is priced per pound. Mithral is just a flat +1,000 for light armor. After all, halflings have to pay a grand despite using significantly less metal than a bigass half-orc.

This might break verisimilitude, but so do a few thousand other things.

[WalterGM]

I believe that all flat costs like that are applied after multipliers when pricing gear.

[CigarPete]

Thanks all. I'll go with the lower cost and can discuss it with my VC if it becomes an issue.
