Deathbringer Masterclass Guide - IdleOn

September 23, 2026

Deathbringer was one of the first Masterclasses released for IdleOn and can advance from the Blood Berserker class. Deathbringer allows you to turn on Wraith mode, where you'll be able to hunt for a new Bone currency that you can spend on various upgrades.

Death Bringer is significantly one of the easier Masterclasses and very simple to master, especially now that World 7 has been released.

Job Advance to Deathbringer

Masterius

To advance to Deathbringer, you need to take your Blood Berserker class to see Masterius in World 6: Troll Playground. Here you'll begin the short Masterclass Questline.

Your task is to defeat 25 different mobs from all of the worlds in IdleOn.

Simply start from World 1, kill one mob and make your way through all the different maps. Or if you can simply head to the World 1 and World 2 Colosseums as they spawn around 15 mobs each.

Once all 25 defeated, head back to Masterius to advance!

Deathbringer Overview

Deathbringer

  • Class Name: Death Bringer / Deathbringer
  • Job Advancement: Beginner / Warrior / Barbarian / Blood Berserker / Deathbringer
  • Family Bonus: +% Total Damage
  • Support Talents: Farming
  • Release Date: January 2025

Deathbringer allows you to farm bones from any mob in IdleOn. To collect bones, you must be in Wraith mode (use the Talent: Wraith Form).

FemurRibcageCraniumBovinae

There are four different types of Bones that drop, with each mob in IdleOn dropping a different type. Use the AFK window to see what bone it will drop.

  • Femur
  • Ribcage
  • Cranium
  • Bovinae

The rate of Bones you collect can be boosted by several different sources within IdleOn (see below).

   

Initially, you'll need to actively farm bones in order to get them. However, the new Charred Bone system allows this class to be played fully AFK once unlocked.

Deathbringer Damage And Stats

When Deathbringer is in Wraith Mode, damage is only affected by The Grimoire upgrades and Deathbringer Talents. That means all your weapon equipments and bonus stats from other sources do not affect your damage.

This also means your Accuracy and HP will be super low when you first start out with Deathbringer.

Luckily, there are lots of different damage-boosting upgrades in The Grimoire.

The Grimoire

The Grimoire Upgrades

The Grimoire is a talent you can assign to your Attack bar, which will then open up a new upgrade menu where Deathbringer can spend it's new bones currencies.

  • +10 Land Ranks for Farming

Once you get to End-Game status for Deathbringer, you can get a whopping +500% Item Drop Rate!

Deathbringer New Talents

TalentTalentTalent

Your new Deathbringer comes with several new attacks that you'll want to learn to use correctly.

The most important of these is the Graveyard Shift tombstone talent. This talent will spawn a bunch of mobs called a Horde; defeat them all and you'll get a temporary boost to Bones found. This talent also gives a massive respawn rate boost (+500% at level 677!).

You can then combine killing Hordes with Detonation; whenever you defeat a Horde there is a chance to trigger a Combustion explosion, which hits mobs near you based on the talent level of Combustion (Blood Berserker talent).

TalentTalentTalent

Deathbinger also unlocks the Ribbon system for Cooking and also has several skill-based talents that affect Farming, a new damage multiplier for all your other characters and a new +% Gold Food effect bonuses.

Deathbringer Guide

Unlike other Masterclasses, with Deathbringer you have complete freedom of what map to choose first. However, you'll want to start right at the beginning in Blunder Hills anyway because your Deathbringer damage and accuracy will be super low.

Your main aim for Deathbringer is to obtain the 1,000 Charred Fragments. When in Wraith Form, they drop from any mob.

Getting 1,000 will unlock the Charred Bone. You'll gain 1 Charred Bone for every hour you're AFK on your Deathbringer.

When the Charred Bone is consumed, it gives you 1-hour worth of bones to spend based on your AFK rate (check the AFK window) of the map you're currently in. When you get to this point, it makes Deathbringer an easy AFK class, and will be a lot faster to progress.

Note that you only gain Charred Bone items every hour of AFK of fighting- that means if you AFK doing a skilling action, you won't get the Charred Bones.

Early Game Progression

World 1 Death Bringer

Worlds: 1-3 (Blunder Hills, Yum-Yum Desert, Frostbite Tundra)

Starting out, you'll want to be levelling your Grimoire upgrades to increase Base Damage, HP, Accuracy and Defence. Since your stats are all essentially reset, this will be slow going in the beginning.

The first 13 Grimoire upgrades all require Femur (the first bone type). A good early-farming spot for Femurs is Valley Of The Beans and The Base Of The Bark.

If you're limited on Deathbringer Talent Points, you'll want to put talent points into the following:

  • Wraith Form (+100)
  • Grimoire (+1)
  • Sentinel Axes (+100)
  • Graveyard Shift (MAX)
  • Detonation (100)
  • Marauder Style (+100)
  • Bulwark Style (+1)
  • Famine O' Fish (+100)

Your main progression-talent is going to be your Graveyard Shift (which increases bone rates and respawn rate of mobs). You'll want to add +100 points into Sentinel Axes for damage-dealing and Detonation.

Famine O' Fish gives you Critical Chance and Critical Damage based on Fishing Efficiency stat; if you have a lot of this already on your Deathbringer, it's worth adding a decent amount of Talent Points early on into it.

Whilst Grimoire does give extra bones, the amount isn't great compared to the amount of Talent Points you have to spend on it. At level 639, it only gives +100% boost. It's only worth investing in if you have a super-high level Deathbringer.

If you're struggling with Accuracy, the Marauder Style talent is worth investing in. You get +% Damage and Accuracy based on the number of Grimoire Upgrades you have.

At some point, you'll also unlock the Knockout upgrade in the Grimoire. This gives you a damage stack for each mob you get a successful knockout on, which is basically unequipping your weapon and killing the mob in one-hit. You have to kill mobs in order however, so if you have the damage, start working on all the World 1 mobs early on.

Mid-Game Progression

World 5 Death Bringer

Worlds: 4,5 (Hyperion Nebula, Smolderin' Plateau)

By now, you should have unlocked your AFK Bones (Charred Bone). You can now skip most of this progression-guide by simply AFKing and using your Charred Bones to get enough Bones to get you to end-game.

However, if you're actively playing Deathbringer and want to get to World 6 faster, then follow on.

The most important stats that will slow you down in mid-game is going to be Accuracy and Damage. You only want to be farming bones on maps you can 100% hit and mostly 1-shot.

The Grimoire offers several accuracy upgrades that you should focus on:

  • Wraith Accuracy (Femurs)
  • Wraith of All Trades (Femurs)
  • Wraith Accuracy II (Femurs)
  • Wraith Accuracy III (Cranium)
  • Wraith Accuracy IV (Cranium)
  • Cranium Hoarding (Bovinae)
  • Wraith Accuracy V(Cranium)

Cranium Hoarding is one of the best accuracy boosters, but it comes very late on in the Grimoire Upgrade list. It gives +% Accuracy based on the total amount of Craniums you have, so to make the most of it, you need to have a decent stash of Craniums in your inventory.

Cranium Hoarding also requires the final bone type: Bovinae.The earliest map you can get Bovinae is Smolderin' Plateau: Niagrilled Falls.

So you're likely stuck with farming Femurs and Cranium bones. Here are the maps for these in Worlds 4 and World 5:

Femurs

  • World 4: Shelled SHores
  • World 4: The Untraveled Octopath
  • World 5: Naut Sake Perimeter
  • World 5: The Great Mlehill
  • World 5: Lampar Lake

Cranium

  • World 4: Mountain Deugh
  • World 4: Wurm Highway
  • World 4: Cocoa Tunnel
  • World 4: Flamboyant Bayou
  • World 5: The Killer Roundabout
  • World 5: Cracker Jack Lake
  • World 5: Miner Mole Outskirts

For mid-game, hopefully your Deathbringer is now at least Level 1,000 and you've gotten several external sources of Masterclass Talent Points. You should be now aiming to max all your Deathbringer talents.

Don't forget, you can increase the Max Level of all your talents by using the World 3 Talent Library.

  • Wraith Form (200)
  • Grimoire (200)
  • Sentinel Axes (MAX)
  • Graveyard Shift (MAX)
  • Detonation (MAX)
  • Marauder Style (MAX)
  • Bulwark Style (200)
  • Famine O' Fish (200)

As mentioned Marauder Style gives both Damage and Accuracy based on the total amount of Grimoire upgrades you have. You should definitely be maxing this skill out now.

If you have Super Talent Points from Legend Talents in World 7, you can also spend these points into the bolded ones. You can reset your talent points by holding down on a talent, so don't fret about which ones to upgrade.

End-Game Progression

World 6 Death Bringer

Worlds: 6, 7 (Spirited Valley, Shimmerfin Deep)

End-Game Deathbringer is mostly focused on World 6 (Spirited Valley). Whilst you can earn bones in World 7, the mobs in this world have such high HP that they are not worth pushing for until Deathbringer is updated with new upgrade options.

Your aim is to get to the final map of Spirited Valley and be able to one-shot Samurai Guardian. This will essentially mean you've maxed out Deathbringer so far, allowing you to farm any mob for the best bone rates.

By now, damage is going to be the only thing slowing you down. Make sure you have been progressing Knockout (+% damage per knockout), Femur Hoarding (+% damage per POW 10 of Femur bones owned), Elimination (+% damage per elimination complete), Annihilation (+% damage per annihilation).

Annihilation is the hardest one to progress (defeat 200 monsters in 60 seconds), but both Knockout and Elimination can give +10,000% damage boost when you progress them to World 6.

Max all talents and use your Super Talents on:

  • Wraith Form (MAX)
  • Grimoire (MAX)
  • Sentinel Axes (MAX)
  • Graveyard Shift (MAX)
  • Detonation (MAX)
  • Marauder Style (MAX)
  • Famine O' Fish (MAX)

Best Maps for Deathbringer Bones

Below we've listed the best maps for farm on for Deathbringer Bones.

Also, when you consume a Charred Bone, it gives 1-hour of bones currencies based on your AFK window. To max out the AFK window, you need to be actively farming using your Deathbringer, getting as many Graveyard Shift stacks for that increased bones % rate.

TIP: You should save your Charred Bones for when there is a Multi Meritocracy week for Masterclasses. This gives you a base rate of 3x bones!

The placement of your Gravestone Shift makes a huge difference in rates.

Map Mob Bone Rate
Spirited Valley - Yolkrock Basin Royal Eggs Femur 1Q
Spirited Valley - Chieftain Stairway Minichief Spirits Ribcage 630T
Spirited Valley - Emperor's Castle Doorstep Samurai Guardian Cranium 200T
Spirited Valley - Sleepy Skyline Ceramic Spirits Bovinae 105T
