I made this Crystallized Shadow farming guide to help out players who want to farm Crystallized Shadow instead of buying them from the Auction House.
Eternal Shadow comes from combining 10 Crystallized Shadow, so if you need Eternal Shadow, you have to farm Crystallized Shadow.
Deathbringer Revenant at the Frostmourne Cavern in Dragonblight is the best source of Crystallized Shadow. This cave was designed in a way that there is always 4 of these mobs up, so when you kill one that would take their numbers below that, a new one will spawn instantly.
IMPORTANT! Follow these tips below because you will double your farming speed:
- Use [Bear Tartare] if you have a level 101 character. The speed boost you get after a kill is 70%, and it lasts for 5 seconds.
- Use a ranged class for farming, or at least a melee class that has a ranged ability with no cooldown and long range. It's better to farm here with a level 101 ranged alt character than with your level 110 main without a good ranged ability.
- Don't loot the mobs one by one, this is probably the most important thing! The mobs will only start to despawn after two minutes, so you can clear the cave 5 times then only loot on your 6th clear. This way you farm a lot faster because you don't have to walk to each mob every single time, and you can loot 6-12 mobs at once. If you have a low level character, and you can't one shot the mobs, this method won't work, you just simply have to farm here normally. (if you can't use the Bear Tartare speed buff, you probably can't do 5 laps in 2 minutes)
NOTE ON SPAWN RATE BUG: It only happened to me once, and I couldn't figure out why, but the mobs stopped respawning for like 1 minute, then instead of 4 mobs in the cave, it was only 1. After around 5 minutes it went back to the almost instant spawn rate. I don't know why this happened, but I just wanted to write a note that this can happen to you.
You can also farm Wandering Shadows at Wintergrasp. But unless you run into the respawn bug I mentioned, Dragonblight is just a lot better place.
If you faction controls Wintergrasp, you can also find Shadow Revenant here. They drop 1-3 Crystallized Shadow every time.
