The structure of the guide is organised in legs tailored to different areas of the game and progression, and timeless sections which can be done at any time in a particular area.
Bold quests will fail if you ignore or leave them once started or nearby.
Underlined quests are unmarked so you will have to look them up in order to know where and what they are as the names will never show up in your journal.

To follow the guide is to follow the procedure outlined in the legs very closely.
Most of the sequences in the legs are very necessary, in ways that are hard to predict,
Some paths are just as valuable as others so you will have a few choices outlined in the legs.

Make sure to be mindful of the Timeless section quests as you can miss/fail them by walking past or being careless. Certain quests can be played in different ways that can lead to missing content (other quests or loot) so consult the guide on the best method.

Ideally, by the end of the playthrough:

• No failed quest objectives
  (WIP: comment any objectives you fail to improve the guide, check wiki for these too)
  
• No failed quests
  
• No missed quests (4 exceptions detailed below)
  
• No missed places of power
  
• No missed items tied to quest areas (or item codes provided)
  
• All Gwent cards available
  
• All paintings and trophies for your estate (except prison poster depending on choice)
  
• Seen all romance scenes and have done It Takes Three to Tango
  
• Cerys is queen of Skellige
  (Alternative to support Hjalmar is not possible without forfeiting a place of power)
  
• All defenders at Kaer Morhen
  OR Keira dies and have done A Final Kindness
  
• Dikjstra or Emhyr rules
  OR Radovid wins, and you cannot do Reasons Of State (and miss the achievement for that playthrough)
  
• Ciri is alive, a witcher, and stays at your estate
  OR Ciri is emperor, visits your estate, and have done Faithful Friend
  
• Olgierd is saved (O'Dimm ending item codes provided)
  
• Anna lives Syanna lives, Detlaff dies, Regis flees Tossaint
  OR Anna lives, Syanna dies, Detlaff lives, Regis stays in Tossaint, and have done The Perks of Being a Jailbird

The quest What Lies Unseen is totally missed because it occurs only as a bad result to other quests and results in a net loss in total quests count (Unseen Elder path)

The following quests each give an increase in total quests but are reasonable to not want to do for story reasons, so are always given as options in the guide:

• A Final Kindness (if Keira dies)
  
• Reasons Of State (if Dijkstra is not shoved - required for the next one)
  
• Faithful Friend (if Ciri becomes empress)
  
• The Perks of Being a Jailbird (if Syanna dies)

Throughout a playthrough are event quests (called Unmarked Quests by the wikis) which don't count as quests in the journal but nonetheless can be missed, so, whenever you enter an area interact with every questgiver you encounter and complete the interaction there and then, but do not straight away do every quest you take from the bounty boards as you can potentially miss quests that trigger in other areas
(namely progressing Following the Thread means you will miss Flesh For Sale, and The Four Faces of Hemdall has more options if done prior)

If you want to play nice like in TW2, try not to kill any trolls you can talk to along the way as there will be plenty of rabid trolls to kill which have the same loot.
Also try not to draw your sword in human encounters, sometimes you can just knock them out with fists.

This game is broken: It's important to note that there are a few major glitches that can happen in your save that can permanently screw up getting 100% completion in any of these categories such as:
- map markers not updating properly
- quest flags being modified post-completion
(sometimes resulting in quests failing after being completed)

You need to be prepared to handle these quirks of the game.
The most troublesome things for me seem to be bandit camps, abandoned sites, and hidden treasures as a few of them seem to stick around long after they have been cleared in completely inconsistent ways.
The best method may be to place saves and do POI methodically at the earliest stage so if there are issues you can always go back and try again (but won't be going back too far).
Sometimes what you're missing is a single loot container (even for things like monster dens or bandit camps).
Also do not use the console command to reveal all POI because that tends to spur on these issues.

Legs are the 'Walkthrough' section of the guide, and the guide's main purpose.
Follow the legs very closely, things contained within the legs must be done in a certain order.
Refer to Timeless and Objectives every now and then.

Before doing a quest of your own volition check to make sure it's mentioned in the timeless or safe section, or otherwise not mentioned further in the legs. As there may be times where you can do a quest but it would be hard to tell you explicitly not to do them at all those possible points.

NOTE: Any witcher upgrade diagrams you find may break the related quests.
Scavenger Hunt: Gear Upgrade Diagrams quests are missable if you find related diagrams without using the maps to start the quest first of (if you don't follow quest objectives strictly).
There is no natural way to align getting the diagrams in the right order with following the legs so try to do them in order after you've done enough of the legs to make that feasible. (so take note of where the scavenger diagrams are in order to avoid them until you have the quests proper, take the earliest opportunity to buy the scavenger maps)

Before doing anything make sure to simulate a Witcher 2 save for a new game if you want to talk to Voorhis to get access to Ghosts of The Past

If you have already started your game and have not yet completed Imperial Audience:

Work in progress,
single asterisks ('*') in entries means the data has not been added yet
Many lists that should be exhaustive are not yet exhaustive.

Table of every quest pertaining to a certain category and which other quests determine its availability and which quests are its cutoff points.
In order of completion for Main and Legs, in alphabetical order for Timeless and Safe

These quests are required to progress the game.

Have cutoffs so must be done in a certain order

Don't have cutoffs but can still be missed/failed accidentally

Don't have cutoffs and can only be failed deliberately
This list will most likely not be exhaustive.

These achievements are missable in that by 100% completion if you don't have them yet you can't get them, but don't pertain to any particular area of the guide

This is missable because there is a finite and non-repeatable amount of contract monsters you can kill.

This is missable because you cannot enter fist fights you have already won, and there is a finite number of them.

1. As the related quest is known to be bugged, you should get the first diagram from Zuetzer Castle before talking to the Ofieri merchant.

4. Do From Ofier's Distant Shores
   
5. Go to a master armorer (e. g. Yoana in Crow's Perch) and craft the 4 pieces of armor.

Facts are things the game remembers to decide what to do the next time a script (such as a quest) wants to look at past events in the game without directly looking up quest journal events.
The console has the ability to manipulate these facts.
Do either "addfact(fact)" or "removefact(fact)" depending on which facts you want to enable/disable

Examples:
If you would typically get the ciri witcher ending & you sided with dijkstra. To get the Ciri empress ending, you could run, just before reaching the white frost:
addfact(mq3035_free_temeria)
addfact(q110_visited_emhyr)

If you got the ciri empress ending and would like ciri to show up to your estate as if she had the witcher ending:
removefact(q504_nilfgaardians_arrive)
then finish the last quest of B&W
