Other Sources for Status Resistance

Somewhat on topic, the Cygnus Knight link skill(s) gives status resistance - anyone know exactly how it works if you have more than one on your account? I think at level 1 it gives 5% and at level 2 10% status resistance, but the effects are 'lowered' when there's more than one Cygnus Knight on the account. Is it just halved, or something else?

I searched for it remembering I had seen it, but forgot it was me who asked. It's here in this thread, third post. On an unrelated topic, I know there is a way to direct directly to the third post, how is that done?
