Quick help with psionic item cost

[Invader]

How much would a custom item of expansion cost that gives 2 size categories, and 3 size categories?

It needs to be swift action 5/day uses.

[OldTrees1]

Expansion for 2 sizes (3 is not possible): 7pp = 7ml, 7rds and 4th level
Command word: Spell level × caster level × 1,800 gp = 4x7x1.8Kgp = 50,400gp
Charges per day: Divide by (5 divided by charges per day) = x5/5= x1

5/day, Command Word:(Standard action), Expansion 2 sizes for 7 rounds, Cost ~50,400gp. However since this uses the magic item creation guidelines it is not RAW and thus the DM should adjust the cost to reflect the actual value of the item.

I know you asked for swift action. However this is as close as I know how to craft.

expansion lasts 1min per Manifester level, it'd probably be more cost efficient to get a net duration psionic item, but i'm not very familiar with item creation so...

Expansion actually has a built-in pp-increase for making it able to be used as a Swift action. While command activation normally precludes such things, it seems a reasonable upgrade, and magic item creation rules are guidelines. This will require DM approval, however (not that it doesn't ANYWAY).

For 13pp, an augmented Expansion can increase you by 2 size categories as a swift action. That requires at least ML 13. Depending on whether the DM rules that you need to treat the level of the power as per the rules given for creating PsiCrowns, or if you can still keep it as a level 1 power, your final cost will be one of the following:

(ML 13)x(Power Level 1)x1800 gp = 23,400 gp

(ML 13)x(Power Level 7)x1800 gp = 163,800 gp

The guidelines for an item activated a limited number of times per day actually make 5/day cost no less than if you can activate it at will. I suggest keeping it activatable whenever you like, therefore. It will last 13 rounds each time you say the magic word, because it is ML 13.

Base, Expansion lasts 1 round/level. If you augment it for +2pp, it lasts 10 min./level. Until you get to at least 1 day/level, continuously-active items cost more than command-activated ones.

[Biffoniacus_Furiou]

Spell/Power Level (1) x Manifester Level (15 fully augmented) x 2,000 gp (use-activated, command word is always a standard action) x (5/5 per day or 1) = 30,000 gp at 5/day for +2 size categories as a swift action, lasting 150 minutes per use. That gives you 12.5 hours/day that it can be active.

It's 1 round/level (http://www.d20srd.org/srd/psionic/powers/expansion.htm) after the errata (https://www.wizards.com/default.asp?x=dnd/er/20040125a).

Spell/Power Level (1) x Manifester Level (15 fully augmented) x 2,000 gp (use-activated, command word is always a standard action) x (5/5 per day or 1) = 30,000 gp at 5/day for +2 size categories as a swift action, lasting 150 minutes per use. That gives you 12.5 hours/day that it can be active.

Wait. Psionic items get free full augmentation? I would have expected the power level (for the purpose of item costs) would depend on the pp cost of the effect.

Boots of Temporal Acceleration (http://www.d20srd.org/srd/psionic/items/universalItems.htm#bootsofTemporalAcceleration) at ML 15 gives you 2 rounds of apparent time, Temporal Acceleration (http://www.d20srd.org/srd/psionic/powers/temporalAcceleration.htm) gives you 1 round of apparent time for 11 pp, or 2 rounds of apparent time for 15 pp. Deconstructing the price of 43,200 gp, we have /6 (power level), /15 (manifester level), /(1/5) (charges/day) = 2400 gp base, or 20% more than stated in the pricing guidelines. Maybe just tack on a 20% surcharge for any psionic item that reproduces a power fully augmented to the item's manifester level.

In that case, the item of Expansion augmented to a manifester level of 15 and usable 5/day should cost 36,000 gp.
