High level summoning question

[blaznee]

So I'm sitting contemplating a summoning heavy Wizard, pretty close to what treantmonks guide suggests.. But how on earth should the "creatures summoned this way can't use spells or spell-like abilities that duplicate spells with expensive material cost" be handled? What is "expensive" in this line?..

It ofcourse doesn't come into play until fairly high level, as there are no high level spells availiable from summons until then.

Also, is there an errata somewhere with bestiary 2 and 3 monsters incl. in the summoning choices?

If the spells they are normally based on has a material component with a listed gp value, it's expensive.

So it means you can't summon genies to grant wishes, or angels to raise dead.
