SAVING THROWS AGAINST PSIONIC ITEM POWERS
Psionic items produce
psionic powers. The DC of a
saving throw against a power from a
psionic item is always 10 + the level of the power or effect +
the ability modifier of the minimum ability score needed to manifest that level of power.
Another way to figure the same number is to multiply the power's level by 1-1/2 and add 10 to the result.
Some
psionic items take advantage of the fact that powers can be augmented to increase their
saving throw DCs. These items are special and have their
cost to create and market price calculated using the manifester's level instead of the power's level.
Most item descriptions give
saving throw DCs for various effects, particularly when the effect has no exact power equivalent (making its level otherwise difficult to quickly determine).
