Occultist Aegis Special abilities with gold cost

[Flamephoenix182]

So going to be playing an Occultist for the first time and I'm not sure how the Aegis special ability interacts with enhancements that have a gold value instead of a +2 value

"Aegis (Su)

As a standard action, you can expend 1 point of mental focus and touch a suit of armor or a shield to grant it an enhancement bonus. The bonus is equal to 1 + 1 for every 6 occultist levels you possess (to a maximum bonus of +4 at 18th level). Enhancement bonuses gained via this ability stack with those of the armor or shield, to a maximum total enhancement bonus of +5. You can also imbue the armor or shield with any one armor or shield special ability that has an equivalent enhancement bonus less than or equal to your maximum bonus granted by this ability by reducing the granted enhancement bonus by the appropriate amount.

The item must have an enhancement bonus of at least +1 (from the item itself or from aegis) to gain an armor or shield special ability. In either case, these bonuses last for 1 minute."

So for example on the srd Shadow is listed under the +2 bonus chart, but it's base price is +3750. Is this a valid choice for Aegis? or can I only choose ones that has a "+X" base price cost.
I'm just curious because for the enhancement +2 enhancement slot it means the only special ability option for the Aegis ability is SR (13)?

Strictly speaking only the '+X' abilities are available to you.

As a house rule I would allow you to add shadow as a +2 equivalent ability for the purposes of these types of abilities, so ask your GM nicely and see if they agree.

You can't add abilities with a gp value. Aegis can only grant those with a +x enhancement equivalence.

As for your other question, once you have a +1 shield and can add +2 equivalence with Aegis, you have several options.

(1) Make it a +3 shield.
(2) Make it a +2 shield with a +1 equivalent ability like Light Fortification
(3) Make it a +1 shield with a +2 equivalent ability like Frosted

That's what I thought. Thanks for the help

You are welcome. Keep in mind that there are lots of other special abilities that aren't listed in UE. Most of them can be found at Archives of Nethys or at d20pfsrd. Aegis and Legacy Weapon keep getting better with each new option - unlike abilities such as Arcane Pool. This is one of the many, many reasons that I love this class.
