How do wizards cast spells which appear on their spell list when it has a divine focus component?

Question

What does a wizard do to cast a spell which contains a DF component?

Take magic weapon for example,

Components V, S, DF

Divine Focus (DF)

A divine focus component is an item of spiritual significance. The divine focus for a cleric or a paladin is a holy symbol appropriate to the character's faith. The divine focus for a druid or a ranger is a sprig of holly, or some other sacred plant.

If the Components line includes F/DF or M/DF, the arcane version of the spell has a focus component or a material component (the abbreviation before the slash) and the divine version has a divine focus component (the abbreviation after the slash).

So do wizards have holy/unholy symbols in their spell components pouch or what?

Answer 1

Wizards ignore all divine focus requirements.

Often, the requirement is "M/DF", in which case "M" part is for arcane spellcasters, and "DF" part is for divine spellcasters. One example of these requirements is greater magic weapon spell. Arcane version of "regular" magic weapon spell has only verbal and somatic components.

Answer 2

No

You don't need a divine focus as a wizard. Divine focuses are meant for divine spells only. Sadly RAW doesn't seem to address this. It is however strongly implied by the definition of a Divine Focus

The divine focus for a cleric or a paladin is a holy symbol appropriate to the character's faith. The divine focus for a druid or a ranger is a sprig of holly, or some other sacred plant.

This definition states what counts as a divine focus for these classes. Wizards are not mentioned, in fact only divine spell casters are mentioned. Thus by RAW wizard don't even have a way of supplying a divine focus for a spell.
