Collectibles - before you begin | Boss Battles Castlevania: LoS 2 Guide
Last update: 11 May 2016
The process of collecting all the treasures hidden in the game (collectibles) was divided into two parts, called "first pass" and "second pass".
First pass - the collectibles described here are only the ones you can grab while not doing any backtracking, using only those skills you have at your disposal at a given time. The collectibles described in this part are the same ones you can find in the walkthrough section of this guide. The "first pass" section was divided into 3 groups: Gems (Life, Void and Chaos Gems), Memorials and Diaries and Piles of Sacrifice and Dungeon Keys. They are further divided into subsections, depending on the mission they can be found in.
Second pass - basically meaning backtracking. In this section you can find all the locations of all the collectibles available in the game and which you can't pick up on your first try, without visiting some places again. This section assumes that you have all the skills (Void and Chaos Magic, Mist power and double jump) and location unlocked (after the Zobek fight). A lot of location revisiting awaits you here, because there's a possibility that some new place was opened (or appeared). The section called "second pass" was divided to 8 parts, each representing a different district available in the game. It was described in such a way that everyone will be able to find what they need (each chapter assumes that you will begin it in a easily accessible, characteristic place).
Author's note: I assumed that no one would want to go back through all those places each time they have unlocked a new skill. I decided to describe the process of backtracking only when you will unlock access to all the skills and areas available in the game - which happens to be right after the Zobek fight. A few tips before you start the search:
Whenever it is possible, visit Chupacabras' store to restock on relics (especially Dodo Eggs) and Dungeon Keys.
Don't begin backtracking when you haven't unlocked all the skills (the last one being the double jump), because you won't be able to get to large number of them and it will end in a waste of time and unnecessary frustration.
To check your progress of collecting treasures, enter the Travel Book and open up the World map - every district will have a "x/y" number next to it, meaning the number of collectibles found (X) and available to collect (Y).
