Setting change: No spells that cost xp

[Particle_Man]

I assume that a setting that lacks spells that cost xp would be a deadlier setting, as that cuts out the easier ways to bring someone back from the dead, heal ability drain, etc.

What else would be different?

Edit: Assume also no psionic powers, etc., that cost xp either.

Given item creation invariably costs XP, are all magic items locked out too?

[Zanos]

The typical raise dead and healing spells cost gold, not XP.

Off the top of my head it's generally spells that create permanent magical effects that cost XP.

No Wish, but most settings don't take Wish into account anyway so little change there.
No Limited Wish means some conditions are a lot nastier; you need a 17th+ level Cleric as opposed to a 13th level Sor/Wiz.
The combination means that certain conditions are only removable by divine casters.

No Permanency, which might lead to somewhat less magical traps/defenses around.

No Planar Ally and no calling-mode Gate - kind of significant, it means divine casters don't have much Outsider help beyond Summon Monster, meanwhile Sor/Wiz can still bind things. With Gate gone, Greater Planar Binding is the peak of binding power, so things with 19+ HD are safe.

No Simulacrum is huge in CO terms, but since (like Wish) no published setting considers the implications of Simulacrum, it wouldn't really change them.

Atonement can only be used on people who changed alignment by unintentional acts; if it was deliberate they're SOL.

No Awakened animals or trees, unless there are naturally occurring ones.

No Commune could have an effect, that's a major line of communication to the deities gone. Again, arcane magic gains ground here - priests can't tell you what their god really thinks, but a Wizard with Contact Other Plane potentially can (albeit with some risk).

And no Vision - meh, haven't seen that one come up a lot anyway.

That's it for core; not actually that many spells with an XP component.
