To reflect this special awareness, psi-spellcasting is represented by a new catagory of feats called psi-spell. Although similar to metamagic and metapsionic feats, psi-spell feats require both arcane spell slots and psionic power points to use, and some also require the ability to cast specific spells or manifest certain powers. The cost of using the feat can be eeither spell levels, if the feat is used to enhance a psionic power, or psionic power points, if it is used to enhance a spell. To "spend" a spell level in this way, the caster must voluntarily give up prepared spells equalling or exceeding the requisite spell levels.
Spells spent by a spellcaster who prepares spells are given up when the psi-spell is prepared. Spells spent by a caster that doesn't prepare spells are given up when the psi-spell is cast. Casting a psi-spell for these latter casters does no increase spellcasting time like spontaneously casting a spell affected by a metamagic feat. Power points spent to apply psi-spell abilities are likewise spent when the spell or psionic power is cast. Spent spells care not cast, their energy instead goes to fuel the psi-spell.
A psi-spellcaster cannot elect to use extra power points to apply a psi-spell feat to a psionic power or vice versa. Both eneries must be present for the feat to work. Normal metamagic and metapsionic feats can still be applied normally to powers and spells affected by a psi-spell feat, and regular limits on power points spent per round still apply as normal.
So, what's my question here?
Basically, since I'm exploring the fullest extent of items that store spells for later use, I have discovered certain combinations that allow you to put metamagic on powers and metapsionics on spells.
Which beings to mind, Psi-Spell feats from Dragon #313.
Now, from the portion that is in bold, I conclude the following:
1) They are similar to metamagic/metapsionic feats, with the exceptions listed above. That means they are treated as metamagic/metapsionic EXCEPT as written above. So, they can be applied to a scroll or a powerstone, as long as you have the feat:
CHAMELEON CRAFTING [ITEM CREATION]
- DRAGON #349 (3.5)
You can craft magic items that can duplicate psionic powers, or psionic items that duplicate magic powers.
Prerequisite: Any one item creation feat, ability to cast 1st-level spells, ability to manifest 1st-level powers.
Benefit: You can place any spell or a power that you know into any items you create. The item crafted determines if the effect is magical or psionic. The XP cost for an item created with this feat equals 1.5 times the item's standard XP cost.
Example: A psion/sorcerer with the Imprint Stone feat could create a psionic shocking grasp stone. Likewise, if the same character had the Brew Potion feat, she could create a magic potion of my light.
Normally, you couldn't add a psi-spell to a scroll, because it couldn't take power points, and you couldn't add a psi-spell to a powerstone, because you couldn't add spells to it. With the addition of Chameleon Crafting, "You can place any spell or a power that you know into any items you create." Thus, you should be able to add psi-spells, if you are willing to pay the additional cost.
2) The second part in bold indicates that spellcasters who have to memorize spells has to pay for the power points upon memorizing the spell modified by psi-spell. This indicates that once done, you cannot remove the psi-spell later. Once committed, it is part of the spell, just like a metamagic or metapsionic feat.
Since I am trying to investigate all possible combinations of Metamagic and Metapsionic feats in various forms of Spell Storing items, it seems obvious to also add psi-spells, since they appear to also be a form of Feat that could be added to spells and powers.
If so, one would calculate the cost based on both aspects of what is paid.
For example, A psi-spell that was 3rd level with a CL of 10 that had 9 power points added to it to fuel the psi-spell effect, would be a scroll with a cost of ((3 x 10) + (3 x 9) x 12.5) x 1.5 gp
Now, admittedly, this would get horribly expensive very quickly, but I'm not here to discuss the cost effectiveness of such combinations, just if said combinations are possible and can be created. If so, I need to add an entire section on how to combine various Metamagic, Metapsionic, Psi-Spell feats together.
or am I missing something obvious?
