The New Plague is a Horde quest for Ruins of Lordaeron, the new Scourge dungeon in the ruined capital above the Undercity. An apothecary wants a sample of venom from a spider that is said to eat through undead flesh. You get it from Witherfang, the first boss, so this is the quickest quest in the dungeon to finish.

It is not the Howling Fjord quest of the same name from Wrath of the Lich King. If a search sends you to a level 70 quest, that is the wrong one.

Step by step

  1. Finish A Recipe For Death. Theodore Griffs gives a three-part chain of that name (levels 12, 15 and 18). The New Plague only shows up after the third part.
  2. Take The New Plague from Theodore Griffs in the Apothecarium.
  3. Pick up the other Horde quests for the dungeon before you go in. Light’s Justice (Royal Quarter), A Frightened Request (The Sepulcher), The Wrath of Rath’mael (Tirisfal Glades) and Crest of Lordaeron are all done in the same run. See the full list on our Ruins of Lordaeron guide.
  4. Enter Ruins of Lordaeron and clear to Witherfang, the large spider that comes with a spider escort and two broodlings.
  5. Kill Witherfang and loot the Highly Toxic Strain from the corpse.
  6. Return to Theodore Griffs in the Undercity and pick your reward.

Rewards

Choose one:

  • Plaguefang: one-handed sword, 18–34 damage, 2.1 speed. On hit it can poison the target for 2 Nature damage every second for 10 seconds.
  • Blight Gloves: cloth gloves with caster stats.

You also get about 5,450 XP. No reputation is listed for this quest.

Tips / common problems

  • No quest on Theodore Griffs? You have not finished A Recipe For Death yet. The chain starts at level 12, so a character who skipped Tirisfal and Undercity quests may need to catch up.
  • Witherfang heals itself. Its Leech Poison drains health over 40 seconds and heals the boss. Cure poison if your group can, and kill the small spiders first.
  • The strain is a quest drop. Everyone on the quest can loot their own. If it did not drop for you, check that you had the quest when the boss died.
  • Do it in one trip. Witherfang is the first boss, but the other Horde quests take you to the end of the dungeon. Take them all before you enter.

Questions & answers

Where does The New Plague start in WoW Forever?

Theodore Griffs gives it in the Apothecarium in the Undercity (around 46.6, 71.8). He only offers it after you finish his A Recipe For Death chain, so if you do not see a quest marker on him, do that chain first.

Where is the Highly Toxic Strain?

It drops from Witherfang, the big spider that is the first boss of Ruins of Lordaeron. Kill it and loot the corpse. The quest item is not a random drop from the trash spiders.

What is the reward for The New Plague?

You choose between Plaguefang, a one-handed sword with a poison effect on hit, and Blight Gloves, cloth gloves for casters. The quest also gives about 5,450 XP at its level.

Can Alliance do The New Plague?

No. It is a Horde quest from the Undercity. Alliance players in Ruins of Lordaeron have their own quests, such as Abominable Creatures and Bloodied Insignia.
