Warforged power crystal component questions

[mabriss lethe]

In Magic of Eberron, There are some psionic warforged components, one in particular stuck out in my mind, The Power Crystal. Short version is that it allows psionic characters to manifest a power 1/day using their own pp reserve. Now, for the questions:

1. Since the character is using an item and not manifesting directly, does the character pay the EXP cost if a power has one?

2. Can a character with no manifester level, or one normally too low to manifest the power manifest from a stone as long as they have access to a suitably high pp reserve?

3. What exactly is the limitation of the phrase in the text, "This power is treated as a normally manifested power, with all the attendant effects"?

Here's the relevant text block:


Activation: A power crystal stores the imprint of a psionic
power. Once per day, you can use the power crystal to manifest
that psionic power, using your own power point reserve or
any power points stored within your body, if you are a psiforged
(see the Psiforged Body feat, page 51).
Effect: The power imprinted in the crystal is manifested
using power points supplied by you, and the specifi c
effect depends on the power used. However, you cannot
augment this power or enhance it with metapsionic feats.
This power is treated as a normally manifested power, with
all the attendant effects.
If you do not possess enough power points to manifest
the power stored within a particular power crystal, you gain no
benefit from it.

1) "This power is treated as a normally manifested power, with all the attendant effects." I'd say yeah, you're paying for XP.

2) Following the same clause, you'd need a manifester level high enough to manifest the power.

3) It means it works exactly like normal manifesting, except you can't augment it or use metapsionic feats with it. However, you also don't need to know the power since the crystal itself provides that.
