Death Note & Multikill Explained

Last updated or checked by author:

The Death Note is a useful addition that activates once you reach World 3 and it boosts your AFK kills depending on how many monsters you have defeated in each world.

The more you kill, the higher your multikill multiplier becomes, meaning you will get through portals faster and get more XP and more monster drops.

There are also a few achievements that will give higher bonuses, depending on your Death Note progress.

World 6 brought along BoneJoePickle and with it, a whole new page for the Death Note boosting multikill tiers in every world! Scroll to the bottom of the article to find out how it works!

Death Note Structure

How Multikill and Tiers work

Multikill is directly correlated to your characters damage as well as various multikill bonuses you obtain from the Death Note itself and other sources across Idleon.

You can see your current multikill tier in any map by checking the bottom of the Away Info window.

The kill multiplier goes up once your damage reaches the required amount, the first Tier being 2 times the current maps monsters HP.

Every tier requires double the damage of the previous tier, meaning the difficulty rises exponentially. So if your current multikill tier requires 10x the monsters HP worth of damage, the next tier requirement will be 20x the monsters HP.

The progress bar at the bottom of the Away Info screen shows your characters maximum damage on top of it, which you can also find from your characters info screen.

Your multikill rate from the Death Note and the other sources that boost multikill percentage is then multiplied by that number.

In the images above, the characters damage is over 23 billion which is rounded up to 24B, which can be seen in the Away Info screen, hitting the 31x multiplier.

This multiplier is then multiplied by all possible Multikill multipliers, resulting in a Multikill percentage of 10570%, which is seen above the tier progress in purple text.

All of these multipliers are automatically added to the Kills/Hr count at the top of the AFK Screen so you don’t need to calculate anything yourself.


You must have 100% hit rate and your maximum damage must be at least double the enemies health to start getting multikill tiers.

Death Note Structure

How Death Note Works

The Death Note is unlocked in World 3, which rewards you with additional multikill percentage based on how many of each monster you’ve killed in each world.

It is good to note that these percentages are World dependent, so if you reach +150% additional multikill percentage from World 1 mobs, that will only affect your kill count when fighting in World 1.

Below you can see how many times you need to kill a monster to reach the next bonus.

TierTotal Kill
Death Note Skull 125K+1%
Death Note Skull 2100K+2%
Death Note Skull 3250K+3%
Death Note Skull 4500K+4%
Death Note Skull 51M+5%
Death Note Skull 65M+7%
Death Note Skull 7100M+10%
Death Note Skull 81,000M+20%
+5% Total Damage

While the tier bonuses are separated by Worlds, the kill counts and bonuses are shared between all your characters.

Obviously you can also use Time Candy to boost your kill counts in Death Note.

Eclipse Skull

The final black and gold skull or Eclipse Skull is unlocked in World 4, in the Rift, and it requires 1B kills, but also gives additional damage to all characters. Click the link above the see the requirements of unlocking the reward in the Rift.

Other ways to increase Multikill

As with every stat in Idleon, you can also increase your multikill percentage through many other means aside from the Death Note.

Obviously the main way to increase it is by simply increasing your damage, but since there are countless ways to boost damage, we will only cover the ways to directly increase the Multikill Count.

Starting off with achievements, there are 3 that will boost your multikill percentage.

Just Passing By Achievement
Just Passing By
Pass 30 rooms in the World 2 Party Dungeon.+2% Multikill for all WorldsWorld 2
Wazzzzam! Achievement
Get ‘Wazam‘ 125 times in the World 2 Party Dungeon.+6% Multikill for all WorldsWorld 2
Too Cute To Live Achievement
Too Cute To Live
Kill all Sheepies within 20 sec of entering the map.+5% Total MultikillWorld 3

Once you reach World 4 and get your hands on Breeding, there are 4 different Shiny Pets that will give you a boost to multikill percentage.

Shiny Pet NameUnlock Order

Pet #8
Rat Monster Animation

Pet #17
Bloque Monster Animation
World 3
Pet #6
Dedotated Ram Monster Animation

Pet #16

All of the pets above add +1% to multikill per level, so together they will add up a significant amount once leveled up to 6. Leveling a pet higher than that takes a lot longer in comparison to the early levels.

When it comes to gear, there are a few multikill boosters, but they’re not easy to acquire and in general other bonuses are simply much more useful.

The Recipe for the Nuget Cake Fedora is received by completing the World 2 achievement called Nuget Nightmare which requires you to get a Nuget Cake (1 in 20K chance) from a Crabbycake monster without using auto attack, which can take ages.

As you might notice, the Pincer Hand Chain can be acquired by buying chains from the Party Dungeon shop or as a Dice Drop from a Party Dungeon. Only a Tier 2 chain can drop this specific multikill chain, but you can have 2 of the same chain on one character.

The rest of the possible multikill bonuses are spread out the game, so we added them into a single convenient table below.

As you might notice there are tons of ways to buff your multikill in each world, many stronger than others. Boosting these is very important as the Tiers you can gain by simply boosting your damage increase exponentially and you will hit a wall fast.

World 6 Jade Emporium & BoneJoePickle

Once you reach World 6, the first thing you do is go to the new Vendor and check what he has for sale. The first item is the spooky BoneJoePickle.

BoneJoePickle Icon
Multiplies miniboss HP by 1.1x and stacks with other BoneJoePickles.

Must hold in character inventory while fighting boss to have any effect.

Sadly you can only buy 1 per day, but make sure to buy one every day.

Now you might be wondering why you should care about this when it comes to multikills, but that comes to play when you check the Jade Emporium shop where you can buy bonuses with Jade earned from Sneaking.

Revenge of the Pickle Upgrade

(16th upgrade)
Adds a new miniboss page to the left of
World 1 in the Death Note.

Each BoneJoePickle in your inventory
counts as +1 boss kill in Death Note.
Jade Coin 11.7B

So once you manage to buy the upgrade, you get a whole new page in your Death Note and the best part about it is, that it gives multikill bonuses to every world, unlike the other pages which only affect that specific world.

BoneJoePickle Death Note

On the right you can see how many kills you need per point and each point grants you +1% Multikill per Tier for every World!

You might also notice that stacking the pickles increase the miniboss health, so when you have tons of pickles, your damage needs to be ready for the HP scaling.

Remember to keep the pickles in the inventory of the character you fight the boss with or you get no progress!
