Simple question for you chaps. Would a swashbucklers combat flair work against someone if they don't speak the same language? It sounds verbal and it's a charm test so there is some confusion in our group. Thanks in advance.

I believe it's up to the DM. On the one hand, the swashbuckler's ability could be verbal, so if the target doesn't understand the language, they may get a bonus to their willpower roll.

However, the swashbuckler could also use the weapon they are using to charm the target. For example, a flourish with a sword could be interpreted as a charm action, so the action could also be non-verbal. Fancy sword moves are somewhat universal in their intent.

In essence, ask your GM.
