Dragon main coder Drake: Oh, i didn't said a thing....
have you readed about the 5% possibility to get nothing? Well... for each party member of your party that is already subbed (or don't have the quest) the % raises (up to 50% in the worst case of only one player in the whole party that needs the horn).
This should help to build party of players that REALLY need the horn. (a full party of players that have the quest to get the horn have the chance to get nothing equal to 1%).
So, at the end, bigger chance to get horn is make big party of players with the quest to complete. (this is for the two golky, not the ToI one)
He says two because he added 2 more later
