Blood Oath Walkthrough

Welcome the Blood Oath walkthrough on Gamezebo. Blood Oath is a hidden object adventure game played on the PC developed by TechFront and published by Merscom. This walkthrough includes tips and tricks, helpful hints, and a strategy guide to how to complete Blood Oath.

Blood Intro – Game Introduction

General Tips

It should be immediately noted that Chapter 8 of this guide deals with the end of the game and the alternate ending, and the decision to either feed or not to feed. For the purposes of this guide, “Not to Feed” was chosen. While the gameplay varies slightly between the two choices, most of the same items are shared between them and thus only one decision will be formally covered.
This particular title features a series of achievements. All are locked at the beginning of the game yet their descriptions and requirements can be viewed from the main menu.
A clicking penalty will be enforced if there is too much random or sporatic clicking.
Hints are unlimited and recharge. You never have to worry about running out. Click on the Ankh at the bottom right corner of the screen to use a hint. If you don’t know what room to go to next, you can open the Map in your Book (Tome of Culadra) and click the hint button and it will reveal the next location.
When searching for items, there will be an illuminated light above them on the list at the bottom of the screen if they can be found in that room. “Sets” will also become illuminated of a piece of it is in the room in which you’re standing.
Interactive items will appear redder and redder the closer you bring the mouse: click on them to receive a hidden items list.
The Book in the bottom left corner of the screen, also known as the Tome of Culadra, can offer you a few special features. One, you can review the story via the main journal area. Two, you can view a Map that will show you where you are and if there are blocked doors, etc. Lastly, you can choose “mini-game” to play a sort of bonus game that will give you play bonuses, such as faster hint recharging times. The Tome of Culadra will be elaborated upon further in this guide at the end of Chapter 1.
Various Cards can be collected to add to the Tome of Culadra. These will be outlined with a square shape in the guide instead of a circle. If there are cards hidden in the room in which you’re standing, a gem on the cover of the book will glow. It will cease to glow once you’ve collected all the cards in the room. Keep an eye out: not only do they offer handy bonuses, but there’s an achievement for collecting all of them.
Some areas and items can only be discovered in a particular order. Refer to the guide below for such items.
Item locations in this guide will be marked with a colored X. Circled objects of the same color are to be used on the same colored X.

*An Explanation of the Tome of Culadra:*

The Tome of Culadra is a “living book” that will aid you throughout the course of the game. There are 3 main sections:

Minigame: Earn bonuses by creating chains of symbols. Search rooms within the game for additional cards: the gem on the cover of the Tome will glow when there’s cards left in the room. Allign the cards so that the symbols touch their own kind (like dominos): this will earn you bonuses. Longer chains will provide stronger bonuses. Create a chain of 16 with all the symbols to earn the maximum number of bonuses. The following bonuses correspond with the following symbols:

? Ankh = Faster Hints

? Blood = Higher Scores

? Moon = Quicker Powers

? Death = Shorter Click Penalties

Logbook: This section of the Tome concentrates on the story and events at hand. It may also contain subtle hints and explanations.
Map: The Map can be viewed to show your current location and where you should go next. Specific doors and boundaries etc are shown on the map. If you don’t know where to go next, you can click the Hint button while the map is open and it will show you the next location.
