What happens when someone uses a Spell Lattice

[BretI]

The Spell Lattice description says that:

Quote:

A spellcaster who uses a spellbook or formula book can copy the spell from a spell lattice as if it were a scroll. Doing so expends the spell from the spell lattice.

So does this destroy the item? If it doesn't, does that a different spell can then be placed in the lattice?

I'm trying to determine the relative advantages of the Spell Lattice and the Page of Spell Knowledge for a spontaneous caster. Seems like there will be some pricing differences for some spells, but I'm wondering what other differences may matter when choosing between the two.

Since the spell is chosen when the item is created, it seems to be a one-time thing. If you want another spell lattice, you have to make or acquire another one.

Also, the pricing appears to be identical (spell level squared times 1,000 gp), so I'm not sure what differences you were referring to.

I would stick with the page as you only need to bear it rather than wield it.

Spell Lattice is useful for arcanist's. Since if you hold it is considered a spell prepared for an arcanist. A page of spell knowledge doesn't have this option.
Spell Lattice is useful for an arcanists.
Page of Spell Knowledge for sorcerers.
A page of spell knowledge on the other hand would only let an arcanist* know the spell so it would have to be one of the spell's prepared for the day for the arcanist to use it. Even then it's vague since arcanist spontaneous cast spells, but they need to prepare spells for the day.
*Not entirely confident on this probably best to ask a GM to see how they would rule it in their game.

So the spell lattice is mostly about allowing Arcanists to have more spells at the ready?

Guess it is Pages of Spell Known for my Summoner then. Everything except the fluff description is better about the page.
