[RPG] Determine the DC of a magical item


I am a CL7 Wizard and want to create a Wand of Silence and just do not know how to determine the DC of the silence spell.

I create the wand together with a CL4 Cleric since the spell is not on my list.

Is the
DC 10 + 2 (Second Level Spell) + 6 (Int value of the wizard) or 3 (Wis value of the cleric).

During the creation a second question occured. Can I heighten the DC by casting Fox Cunning on me before I do the spellcast check for creating the item?

Magic Items on Saving Throws Against Magic Item Powers says

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.

Thus the effect created by the typical wand of silence has a save DC of 13 (base 10 + 2 for a 2nd-level spell +1 for a minimum casting ability score of 12 that's needed to cast the spell).

Increasing the ability scores of the folks making magic items doesn't typically improve the saving throw DCs of the magic items they create. Also see this question.
