This is my Witcher 2 roadmap to help you plan to get your 1k in 2 playthroughs. It’s not an achievement guide, but I did add small descriptions on how or what. The list is in order when you can first get them or when I got them. I also broke it down in the 2 different paths.
This game requires 2 playthroughs to 1k it. (~1.75 actually if you start on Dark). Reason is, near the end of Chapter 1 you have to pick a path (Iorveth or Roche).
I suggest to start on easy/normal on your first, because Dark can be very annoying/unforgiving if you start here right away. Since you have to play it twice anyway, easy/normal is a good way to start and enjoy the game. Then you can rush through Dark in ~10 hours if you want.
I also suggest going with Iorveth on your first normal/easy playthrough, cos I found it easier than Roche's path. The steps to 1k are easy enough and they are:
Step 1: Normal/easy playthrough with Iorveth and kill the trolls.
Step 2: Dark playthrough with Vernon Roche and spare the trolls.
Step 3: Finish 30 arena rounds.
-Arena is separate from the game, handy to get to fight 30 to try out skills and the fighting.
-For your first playthrough, kill all (3) trolls. Trollslayer will pop during chapter 2.
-Spare all 3 on your second (there’s actually a 4th with Vernon, not sure if he counts)
-Read this WIKI and try to get as many abilities as you can on your Dark playthrough.
-Try do do most of the quests on your first playthrough to reach level 35 for Guru.
-I went 95% magic on my Dark playthrough, once Igni is upgraded the game becomes a lot easier.
-Perfectionist is easy to get at the start of chapter 2, when you are under a magical umbrella. Just tag 10 enemies without getting hit.
-Miser, this is not cumulative, you need 10k at once and it’s easy if you loot/harvest a lot.
-Try to save up some points during chapter 2 (8-9 I think), make a save and get the mutant ability. Then reload and spend them like you want to.
For getting the 3 adrenaline ability achievements (the mutant/heliotrope/group finisher) It's much for practical to instead do the quest From a Bygone Era as you are able to fully respec, simply make a save before you talk to the Operator. This is just easier than holding onto points imo.
-Ricochet and Focus need to be unlocked in the trees. Once unlocked, hold block when you isolated some archers and it pops when you killed 1. For Focus, lock on to an enemy and press A when indicated.
Note: some achievements take a few seconds to unlock.
-Eagle Eye, when the king asks you to aim the ballista, look for a small character in the distance.
Chapter 1 missables:
-Librarian, just keep your eyes open during the asylum quest. Last of the 4 pages is in the wraith room.
-Man of the Shadows, during Indecent Proposal. Take your time and don’t get detected, stun all the guards you can. Make sure to find the kayran trap part at the end outside or you will miss Artful Dodger later!
-Artful Dodger, just press A where it shows you to plant the trap to instakill a tentacle when it hits. (must craft kayran trap beforehand ofcourse)
Important: finish the nekker and endrega quests for Pest Control in chapter 3!
Chapter 2 general missables:
-Friend of Trolls/Trollslayer, just either kill or spare trolls during an entire playthrough.
If you want to save them, you will have to finish their quests and save the last troll from enemies.
Chapter 2 Iorveth missables:
-Blackops, don’t get detected while trying to sneak through the Kaedweni camp.
Important: finish the harpy nest quest for Pest Patrol in chapter 3!
Chapter 2 Vernon Roche missables:
-Tourist, just follow Zyvik around.
-Gladiator, don’t forget to drop by here and win all 4 fights. (Talk to Proximo)
-Heartbreaker, for free eboobs, after you defeated Ves, go visit her at Roche’s camp. Pick the right options (very obvious) and do what you want.
-Necromancer, there's 5 (6) easy parts you need to complete.
-Reasons of State, just pick the right option to get this bleepie. It’s during the cutscene after you fight the king.
Important: finish the rotfiend quest for Pest Patrol in chapter 3!
Chapter 3 general missables:
-Pest Control, this pops after you turn in the gargoyle quest.
-Sensitive Guy/Witch Hunter, make a save when you are heading to the tower with the dragon. Pick either to remove or leave the diamond when you meet up with Síle and reload.
-Avenger/Old Friends, make a save before you walk up to Letho, reload and pick other option.
Chapter 3 Iorveth missables:
-Spellbreaker, start by helping Philippa out of the prison. Don't go rescue Triss!
-Dragonheart, choose "Walk away".
Chapter 3 Vernon Roche missables:
-Kingmaker, don't go rescue Triss!
-Being Witcher George, choose "Kill the dragon".
