candidate expression

[Mergon]

I am trying to create a candidate expression which allows the player to pick 1 of 4 skills that he or she is not proficient with.

I am sure I have done this before, but for the life of me I can't remember how and I can't find an example . . . <sigh>

The skills are: Deception, Intimidation, Insight, and Persuasion.

Any help would be appreciated.

I think a good example might be to look at the Rogue Expertise ability but you're going to be like
(thingid.skDecepept|thingid.skIntimid|thingid.skIn sight|thingid.skPersuas) & !Helper.Proficient

as always, timing will be the rough thing.
