[@Scarifar], mechanically speaking, I think a broader Domain may allow you more freedom when it comes to applying Domain Boosts. Laughter doesn't seem like it would give you that much freedom when it comes to that, as the actions one could take that reasonably tie to that are very few. An example could be Revelry, which would broaden your repertoire of boosted actions from pretty much only jokes to celebrations and joyful events of all kinds.

However, if you feel pretty strongly about keeping Laughter as a domain, I'm not gonna stop you. I do need you to add one or two examples of concrete actions that the Domain of Laughter would give your character before approving the sheet, tho.
