Get ready to hate your life.

Not sure if there is a specific mob that drops the hearts, but after about 5 or 6 hours of grinding our here with a partner and the node at 10 AND a yellow loot scroll...... I have a grand total of 5....... I have 11 Embers of Despair to make the Dead God armor.... think about that, at this rate I will have 100 Yellow grade rare items before 50 blue grade rare items..... I think someone needs to take a look at the drop rate on these since you need 50 for crafting Garmoths heart.

It should also be noted that these mobs are in three pulls, and all but 1 have range attacks that can take you to 2/3 or half life in the blink of an eye if you are not light on your feet and paying attention to literally every mob you are in combat with. I have 316 DP and with full buffs these mobs still force you to seriously rethink every starting crafting the heart.
