Check: You can use this skill to decipher a power encoded in a power stone or to activate a psionic item. This skill lets you use a psionic item as if you had the appropriate psionic power or feat. It doesn't allow you to use psionic items that require paying power points to operate.

When you're attempting to activate a psionic item using this skill, you do so as a standard action. (See Using Items, Psionics Handbook page 121, for discussions of how psionic items are normally activated.) The checks that you make to determine whether you are successful at emulating the desired factors to successfully perform the activation are instant, however. They take no time by themselves and are included in the activate psionic item standard action.

You make emulation checks each time you activate a device such as a dorje. If you are using the check to emulate a quality in an ongoing manner, you need to make the relevant emulation checks once per hour.

You must consciously choose what to emulate. That is, you have to know what it is you are trying to emulate when you make an emulation check.

Note: In cases described below in which effective level is important, it is okay to have an effective level of 0.

Contact Power Stone: This works just like learning a power from a power stone with the Psicraft skill, except that the DC is higher.

Emulate Psionic Power: This use of the skill allows you to use a psionic item as if you had a particular power on your class power list. To activate a power stone (an object that stores a specific power) or use a dorje, you must have a particular power on your class power list. By using the skill this way, you can use such an item as if you did have the power on your list. Your effective manifester level is your result minus 20. For dorjes, it doesn't matter what manifester level you are, but it does matter for power stones (see page 129). If your effective level is lower than the manifester level, you might fail to manifest the power.

The emulation ability works much like the Use Magic Device skill described in the Player's Handbook, except that it works with psionic items. It does not let you manifest the power. It only lets you use it from a power stone or dorje as if the power were on your class list. Note: If you are manifesting it from a power stone, you have to contact it first.

Emulate Psionic Feat: Sometimes you need to have a specific psionic feat to activate a psionic item. This skill does not let you use that feat. It just lets you activate psionic items as if you had it.

Emulate Psionic Class Feature: Sometimes you need to use a psionic class feature to activate a psionic item. Your effective level in the emulate class is your result minus 20. This skill does not let you use another class's class feature. It just lets you activate psionic items as if you had it. If the class whose feature you are emulating has an alignment requirement, you must meet it, either honestly or by emulating an appropriate alignment as a separate check.
