Scrolls, Devices, and Stats

[AlphaNerd]

So, when casting from scrolls, are the DCs based on your spellcasting stat (assuming you have one), or are they fixed DCs? What about wands/staves/rods, or wondrous items?

From the SRD:

Magic items produce spells or spell-like effects. For a saving throw against a spell or spell-like effect from a magic item, the DC is 10 + the level of the spell or effect + the ability modifier of the minimum ability score needed to cast that level of spell.

Staffs are an exception to the rule. Treat the saving throw as if the wielder cast the spell, including caster level and all modifiers to save DC.

Most item descriptions give saving throw DCs for various effects, particularly when the effect has no exact spell equivalent (making its level otherwise difficult to determine quickly).

Saving Throws under Using Magic Items

So as far as I can tell, a scroll has a DC of 10+1=11 for a first level spell, 10+2+1 =13 for a second level, 10+3+1 for a third level spell, etc, so they have static (and mostly inferior) save DC's. All others (except staves) seem to follow these rules. Staves you get to use your (probably substantially better) modifiers with.
