Death Note & Multikill Explained » Idleon (2024)

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.

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.

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.

Tier	Total Kill Requirement	Multikill Percent
	25K	+1%
	100K	+2%
	250K	+3%
	500K	+4%
	1M	+5%
	5M	+7%
	100M	+10%
	1,000M	+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.

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.

Achievement	Description	Bonus	World
Just Passing By	Pass 30 rooms in the World 2 Party Dungeon.	+2% Multikill for all Worlds	World 2
Wazzzzam!	Get ‘Wazam‘ 125 times in the World 2 Party Dungeon.	+6% Multikill for all Worlds	World 2
Too Cute To Live	Kill all Sheepies within 20 sec of entering the map.	+5% Total Multikill	World 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 Name	Unlock Order
Baby Boa	World 1 Pet #8
Rat	World 1 Pet #17
Bloque	World 3 Pet #6
Dedotated Ram	World 3 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.

Equipment	Stats	Source
Hallowed Tail Pendant	+30% Multikill +1 STR/AGI/WIS +3 LUK 2 Upgrade Slots	Party Dungeon Flurbo Shop
Nuget Cake Fedora	+15% Multikill +1 Weapon Power +10 LUK 6 Upgrade Slots	Smithing (Anvil Tab 2)
Pincer Hand Chain	First stat: +5%, +7% OR +12% Multikill Second Stat: Random Tier 2 keychain stat (can also be more Multikill %)	Party Dungeon Keychain (Tier 2)
Crown of the Gods	+22% Multikill per Tier +18 Weapon Power +65 STR/AGI/WIS/LUK +15% Drop Chance +210 Defence 11 Upgrade Slots (Level Requirement: 510)	Smithing (Anvil Tab 6) (World 6 item, extremely late game)

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.

Item	Effect	Source
Multikill Stamp	+% Base Multikill rate	Many World 3 Monsters (1 in 1.23M)
Clammie Card	0 Star: +1.5% Multikill per Tier 4 Star: +7.5% Multikill per Tier Ruby Star: +9% Multikill per Tier	Clammie (World 4)

Death Note Building	+2% Multikill per Building Level	Construction (World 3)
Balance of Pain Prayer	Level 1: +8% Multikill per Tier Level 30: +31.2% Multikill per Tier	Wave 21 at Clash of Cans TD (World 4)
Purple Salt	Level 1: +3% Multikill Level 10: +30% Multikill	Salt Lick (World 3)
Wood Chip	+15% Multikill per tier	Lab (World 4)

Trilobite Rock Artifact	Normal: +25% Multikill per Tier Ancient: +50% Eldritch: +75% (from The Rift)	Sailing (World 5)

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.

Item	Description	Source
BoneJoePickle	Multiplies miniboss HP by 1.1x and stacks with other BoneJoePickles. Must hold in character inventory while fighting boss to have any effect.	Spirit Village Shop World 6 Spirit Village

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.

Jade Emporium Upgrade	Description	Jade Cost
Revenge of the Pickle (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.	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.

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!

At the time of writing this, there are 6 different minibosses that count for this Death Note.
