Hello,
In the BFD guide for horde, there is a point that asks you to kill Blackfathom Tide Priestess’ for a ‘Damp Note’. I killed these things for about half an hour to 45 minutes and the note did not drop. I researched and it appears that the note will only drop if you have another quest in your log. This quest is called ‘The Essence of Aku’Mai’. After i went and got this quest, the damp note dropped after about 4-5 kills.
This quest ‘The Essence of Aku’Mai’ is given from ‘Je’neu Sancrea’, who also gives a quest for BFD (which is in your guide).
I might be good if you add the quest ‘The Essence of Aku’Mai’ into the horde BFD guide, as it can be done while in the area, and is needed to unlock the ‘Damp Note’.
