Wands contain weaker spells that can be utilized without much issue. These wands can contain any type of spell (Arcane, Psychic, Divine, etc.) and the levels of spells within the must either be 1st or 2nd level.
Activating wands requires a DC 20 Use Magic Device check if the user can’t cast spells. Otherwise no UMD check is needed.
Wands/Staves use the caster’s MAG for spell effects/to-hit and damage.
