What the achievement asks
Defeat Gorak Tul in Waycrest Manor on Heroic difficulty or higher. Ten points, both factions.
Waycrest Manor is the Drustvar dungeon, the house at the top of the zone where the Waycrest family locked themselves in. Five encounters, and Gorak Tul is the last of them.
The five encounters
| Order | Encounter |
|---|---|
| 1 | Heartsbane Triad: Sister Briar, Sister Malady and Sister Solena, fought together |
| 2 | Soulbound Goliath |
| 3 | Raal the Gluttonous |
| 4 | Lord and Lady Waycrest, a paired fight |
| 5 | Gorak Tul |
Only Gorak Tul is named by the achievement, but the manor runs in order, so the run is the whole dungeon either way.
Raal the Gluttonous is worth a moment's attention if you are working through the rest of Drustvar: he drops the recipe for the Heartsbane Hexwurst, the one sausage in Sausage Sampler that no vendor sells.
Heroic or higher, but on one character
Blizzard's wording is "on Heroic difficulty or higher", so a Mythic or Mythic Plus run earns it just as well. There is no need to queue for Heroic specifically.
The eight Heroic dungeon achievements are not account-wide. Four on your main and four on an alt leaves you with nothing. They all have to be earned by the same character.
Once one character holds all eight, the Battle for Azeroth Dungeon Hero achievement they feed into is account-wide, so the grind only has to happen once.
