Caster level of Whisper Gnome Silence ability

[Ulrik]

Spell-Like Abilities: 1/day -- silence (must be centered on whisper gnome's body). A whisper gnome with a Charisma score of at least 10 also has the following spell-like abilities: 1/day -- ghost sound, mage hand, message. Caster level 1st; save DC 10 + whisper gnome's Cha modifier + spell level.

Is the caster level for Silence 1st, just as the other abilities? Or is it equal to the character level of the gnome (default for spell-like abilities)? I don't think it's quite clear.

(Of course, I might just be blinded by the fact that I think that Silence for 1 minute isn't that good, and I'd like to think that it has the default caster lvl to get a longer duration... )

The CL is 1st.

 

[Ulrik]

Oh, well. It's what I should have expected.

Thanks for answering!

It's CL 1st, unless you take the gnome illusionist substitution level called "Gnome Illusion Spells", in which case it's your Wizard level.
