All right this doesn't seem to be working for me. Can you give me more specific details on how to perform this? I found someone in IF with the same pet name as my own. I summoned my felguard, and after I summoned him, I clicked the other felguard, who had the same name, and pressed my demonic sacrifice button. I only received a single buff. Does the other person need to be in your group? Any tips would be appreciated. Thanks.
