Variety is the Spice of Life

This achievement is account-wide. All world quest you complete with different characters will count. World quests become available on character level 110. To unlock World Quest, you need to be level 110, and to complete Uniting the Isles by reaching Friendly with the 5 major Legion faction. (With Patch 7.1 this reputation requirement part of the quest also becomes account wide.) The key word for this achievement is "different" you need to do 100 unique world quest, repeated ones don't count.

There are 7 different factions available to do world quest for:

• 
  
• [faction=1948] (Stormheim)
• 
  
• [faction=1828] (Highmountain)
• 
  
• [faction=1883] (Val'sharah)
• 
  
• [faction=1900] (Azsuna)
• 
  
• [faction=1859] (Suramar)
  
  
• 
  
  
• [faction=1894] (global)
• 
  
• [faction=1090] (global)
• 
  

The first 5 factions are tied to their home zones, for example you can find most of Valarjar world quest in Stormheim. There are only a few exceptions, like [spell=230408] which are part of the opening story of Trials of Valor raid instance and can spawn anywhere on the Broken Isles. The Helarjar world quests give reputation to the Valarjar and the quest location's host faction.

The Wardens is a global faction and their WQs can also be found all over the Broken Isles. Most of their quests are Elite world quests designed for parties and will be challenging if you plan to solo. (At least in ilvl 780-820 starter gear.)
Kirin Tor WQs can also be found in multiple Legion zones with quest types described here. With Patch 7.1 there are new Kirin Tor WQs available but the Kirin Tor emissary quests are offered much more rarely than before the patch.

World Quest Sets (Emissary Quests): For every subsequent day there are factions randomly selected to do a set of quests for. You can see the active factions on your world map's corner. These emissary quests require 4 world quests to complete for the same faction while it's available.

Rewards (for emissary quests):

• 
  
• 1500 net reputation for the emissary's host faction
• 
  
• an item that increases your Artifact Power by 400 (multiplied by your current [currency=1171])
• 
  
• a shiny treasure box that may contain
  
  • 
    
  • a 805-835 ilvl gear (based on your itemlevel)
  • 
    
  • 700-800 [currency=1220]
  • 
    
  • Champion equipment (rare!)
  • 
    
  • [currency=1275] (rare!)
  • 
    
  • Legendary gear (very rare!)
  • 
    
  • [item=140495], the quest starter item for [item=137573] (rare drop from the Suramar Emissary chest)
  • 
    
  
  
• 
  

The factions all include the same type of quests:

- Kill X amount of mobs,
- Interact with X amount of objects / NPCs,
- Loot X amount of stuff,

The only difference is really the environment. A good example for the variety of environment is the ship quest in Stormheim where you also need to kill X amount of mobs but by navigating a sailboat which makes it unique and fun.

Reward types (for world quests):

• 
  
• Gear 805+ to 835+ (based on your current itemlevel)
• 
  
• Artifact Power increasing items (the amount scales with your Artifact Knowledge Level)
• 
  
• [currency=1220] (usually between 300-800)
• 
  
• Low amount of gold (usually 2 digits, elite quests may reward you up to a few hundreds.)
• 
  

Profession World Quests: A special category that also counts toward the achievement. There are world quest for your character's primary and secondary professions too. Those quest are a lot faster and much more simple to complete than the faction WQs. For example, you only need to travel to a specific location and bandage some injured NPCs (usually not surrounded by mobs), or you need to kill a single Fel Infernal to mine its core. To balance the difference in difficulty, profession quests are offered much more rarely than faction quests so there's no way to just farm only those for the achievement.

All the currently offered world quest and the active factions are shared between all players on the same region.

does not seem to count quests on Argus, fyi

Is there a way to Track which world quests you have done and not done for this achivement?

Would be nice to know what I have done so I don't do the repeats so I can get this achivement. could of sworn i saw an /run addtracker for this (not sure if it did what i wanted it to
