Adding 0 level caster class

[Stonejager]

I'm trying to add the ability to cast 4 0-level Sorcerer cantrips to a race. Using the Spellcasting Options section doesn't seem to work as it thinks I have 1 level of Sorcerer, including level 1 spells.

I've also tried the below script:

~ If we're disabled, do nothing
doneif (tagis[Helper.FtDisable] <> 0)

~ Loop through all Arcane classes
foreach pick in hero from Class where "CasterSrc.Arcane"
~ increase caster level
eachpick.field[cCasterLev].value += 1
nexteach

But it generates a 'non-existent component 'Class' referenced by script' error

I thought maybe setting the phase to Post-Levels (Users) would let the script see the Class component but no luck.

Thoughts? Thanks in advance.
