Gnomes add +1 to the DC of any saving throws against illusion spells that they cast. Gnomes with a Charisma of 11 or higher also gain the following spell-like abilities: 1/day—dancing lights, ghost sound, prestidigitation, and speak with animals. The caster level for these effects is equal to the gnome's level. The DC for these spells is equal to 10 + the spell's level + the gnome's Charisma modifier.
