seductive whispers is the quest from blacksmith in aden. you gather spirit beads and then gamble with the blacksmith for an incrementing reward. the more you win, the more adena (and additional stuff) you get. the npc himself gives the reward list in his chat options - as i remember (not sure) it goes 40k-80k-120k- and incrementing further. the problem is that both after 1, 2 and 3 wins i always receive only 7k adena.
