Wakening essences can drop from sources similar to Writhing essence
. This means that you can obtain Wakening Essence from the following:
- Weekly Mythic plus chest (20, highest level cleared doesn't matter).
- Normal/Heroic/Mythic Antorus bosses (3-6 per boss, per week, regardless of lockout. I will assume lfr counts like before)
- Emissary caches (4-10). Emissaries saved from before the quest do count, unopened boxes do not.
- Daily Legion Heroic dungeon (5)
- Weekly PvP rewards, ie: earn 1500 honor in 2s, 3s, and rated battlegrounds (7 from each)
Assuming seven emissaries, a full clear of Antorus, one mythic plus for your cache, seven daily heroics, and all three PvP weeklies, you should be able to earn about 175 essence per week
