SiN-QQ clan skill

If your clan as the skill SiN-QQ, how do you use it? I’ve typed -QQ & -qq and nothing seems to happen. Is it passive or is it broken?

I thought it was passive, but been so long could be mistake.

And I think it only works when more than 1 clan member is on screen. So if 2 or more in same clan are together then it works. Otherwise it’s useless…
