Death Book

Killing bosses is worthwhile again! Each boss in the Death Book provides several upgrades including offline/passive kills, reward multiplier, and more!

The Death Book was added with Version v2.19.0

## Unlocking the Death Book

The Death Book is located in the Terror Graveyard, an area of the Energy Belt unlocked after beating the Super-Terror. Once clicked, it will display this message *"This book is shut by an enchanted seal. Legend has it that this book is filled with ancient magical knowledge."*

To unlock it, you will need the following resources:

* 100.000  Shards
* 500  Light Essence
* 500  Dark Essence
* 100  Strange Essence
* 10  Iridescent Essence
* 300Borb Ascension Juice

\*It is recommended to have 150% Brew Multiplier and 300%+ Brew Critical Chance before brewing  Iridescent Essence. This guarantees 12  Iridescent Essence per brew (3 base  Iridescent Essence\* 4x Multi-Critical Chance), as opposed to having a chance to brew 9 or less  Iridescent Essences and falling short of the required 10  Iridescent Essences for Death Book.

## Passive Boss Farming

Death Book gives timer bosses reward periodically, and is the only way to gain their rewards without manually defeating them. It gives both online and offline reward, but does not work with time skips. Sitting in an offline area while online reduces its timer by 1 additional minute for every minute in the area, effectively doubling rewards gained in the same amount of time. Unlike manual timer bosses farming, death book kills do not drop Cards or Relics.

Passive Boss Farming becomes many times ***better*** manually farming after maxing a Boss's Death Book. You can check your loot per Death Book cycle in your chosen boss's Death Book menu.

## Boss Upgrades

### Upgrade Basics

Each Boss can be upgraded up to Level 10 in six different Points for the cost of some  Light Essence,  Strange Essence or  Iridescent Essence which can be acquired through Alchemy. Requirement for the Upgrades is that you have already killed the specific Boss 25 \* 2n times (25.6k Kills for Level 10).

## Strategy

### Before Unlocking the  Death Book (Part 1)

To unlock the Death Book, we need to maximize our Brewing, so we can get as much  Strange and  Iridescent Essence as possible with every brew. To do that, we need to to make 2  Plasma Crafted sets, using the following distributions:

You should start Brewing  Card Parts, as you wanna have 300 Brew Crit Chance before brewing  Iridescent Essence, so you can get enough for unlocking the Death Book in a single brew, saving a lot of time. To help you reach that goal, purchase all brewing related upgrades in the Gem Shop Gem Shop (Alchemyritical and SuperStirr). After that, you should start saving gems for the Offline Brewing upgrade, in the  Gem Shop Gem Shop. Your goal is to get 5/5 Offline Brew Rate, and 3/10 Offline Brew Count before 8/4, because Offline Brewing works in offline areas. Brew count should only be upgraded to 3/10, as more than that does nothing, because of material cap.

### After Unlocking the  Death Book (Part 2)

*For the rest of this guide, Death Book/Kill Count upgrades will be numbered, for example; 8/4*

Maxing  Witch's Death Book to 10/10 is infinitely better than manually killing witch. But for now, you need to manually farm  Witch kills just a little longer. Get your Death Book to 8/0, first 4 upgrades shouldn't take too long, but it might take some time to get from 4 to 8. Now, move onto Kill Count. You wanna get 4 levels of that. This might take even longer, but it's very worth it.

If you get at least **25 kills/hr** (8/4 should give you enough), AFK in an offline area instead (The Dark Glade is recommended). Being in offline areas effectively double the Death Book efficiency (this is because every minute that passes in offline areas reduces the Death Book cooldown by a minute as well). Now, your goal is to get 10/4. That is the final stretch. After that, you are done with the Death Book for **Energy Belt**. Make sure to keep enough Shards on Witch Essence multiplier so you'll always get at least 3,600 Cosmic Essences 3,600,  3,600 Earth Essences 3,600,  3,600 Leaf Essences 3,600, and  3,600 Water Essences 3,600, and put the rest on Brew Crit Chance%. After achieving 10/4, brewing more  Strange and  Iridescent isn't necessary. You should instead use the DE/LE Brew Set to brew both  Transformation Shards and  Fusion Shards, in order to permanently brew  Card Parts.

### Soul Boosting (Part 3)

*Make sure to follow this part of the guide **only** after unlocking the Fire Fields Portal. That is because the Fire Fields bosses do not gain an increase in damage when soul boosted, and they give the highest amount of Raw Soul Stone per kill.*

Firstly, kill Green Flame once, and unlock "Craft Sacred Leaves" in the  Coal Leaves Shop. Then, craft a fully sharded and ascended Brew Coal Set. (80 Shards on Brew Multiplier and 80 Shards on Brew Critical Chance, although it is possible that you'd still need to shard Witch Essence Multiplier).

Before continuing on with the guide, 100%+ **Heat Resistance** is required. While you can theoretically follow the rest of the guide without it, it's really not recommended.

AFK in an offline area (The Dark Glade is recommended), and level  Witch's Death Book to 10/8. Then, level Green Flame's Soul Boost Chance to 1/10 and level Soul Boost Pity Counter as high as you can. Get enough Raw Soul Stones to get  Witch's Death Book to 10/10. Then, level up Green Flame's Death Book and Kill Count to as high as you can. This is because Green Flame drops 9 base Raw Soul Stone per Soul Boosted kill, and because it doesn't gain an increase in health when Soul Boosted. Before getting enough kills for 4/4, manually kill Green Flame until you get enough. Then, AFK in an offline area until you have enough kills for 10/10 Green Flame's Death Book.

After getting 10/10  Green Flame's Death Book, you wanna start leveling every other Green Flame's Death book upgrade to 10. It's important to know that each stat that Soul Boost Chance, Drop Count and Passive Soul Boost Chance cost Raw Soul Stone after getting 4 upgrades. And since it's relatively cheap, it's not that difficult to get enough Raw Soul Stone to level up from 4 to 10. After maxing Green Flame's Death Book (10/10/10/10/10/10), you are pretty much set on Raw Soul Stone, but there are still things you wanna work on to speed up the process of obtaining them.

### More Raw Soul Stone (Part 4)

After completely maxing Green Flame's Death Book, it's  Spectralseeker's Death Book time.  Spectralseeker's Death Book strategy follows the exact same steps as the Green Flame's Death Book steps, but with 1 exception:

* Since  Spectralseeker's kill requirement is a struggle to increase, you wanna get enough kills for 2/2. From there, it's your choice whether to keep farming  Spectralseeker kills manually (which might be better because of  Spectralseeker Cards), or to afk in an offline area and farm kills passively. Either way, after getting 4/4, AFK'ing in an offline area is the better choice.

After getting 10/10 for  Spectralseeker's Death Book, keep progressing in Soul Realm without focusing on any Death Book upgrade. After getting enough brew stats so you can cap your  Iridescent Essence storage relatively fast, you can easily upgrade all other Death Book upgrades. (credit to nohearu for the stats)
