I'll be here post complete Collectibles Guide.
Castlevania 2 has total 189 Collectibles
. 90 Gems (30 of each variety), 29 City Memorials, 27 Piles of Sacrifice, 24 Soldier Daries and 19 experience Shrines.
The best Way to collect all Collectibles is after beating the Game and before you start a NG+. At the End of the Game you have all Abilities to collect all Collectibles and after beating the Game, you are now in Free Roam Mode and can revisited all Locations (except Agreus Fighting Arena). If you Start a NG+ you lose all your Abilities.
The Gems, Piles of Sacrifice and experience Shrines you have a (total) Counter on the World Map for each Zone where you collect. (Example Bernhards Wing 0 / 19 - 14 Gems, 4 Piles and 1 Shrine)
The Memorials and Diaries are untracked but you can see how many and which in the Loremenu in your Travelbook and with the Namelist below can you check which you have and which not (Name comparison)
For the 19 Exp Shrines you need 19 Dungeon Key, this Keys you can buy in Chupacabras Shop located in the City of Damned Zone.
In my Videos i start in the Map Room of each Zone, collect all Collectibles in one Run and at the End we arriving the Map Room again. So I run, figuratively speaking, a circle in my Videos.
I have a lot of spoilers used here to provide a better overview, simply fold the spoiler from your currently needed. The first Spoiler is always the Video and the second Spoiler is the Timeline with clickable Links incl the Names of all Memorials and Daries.
The clickable Timelinks will open in a new window and the video will start at the time or at the Item. In the Youtube Description you have the same Timeline too. Directly on Youtube dont open a new Window when you click a Timestamp. (Works only there)Sciences District
