The Death Note is a tower you can build in World 3 from the Construction Table. The Death Note keeps track of how many mobs you have killed across all your characters and gives bonuses to collecting resources from mobs.

The Death Note is the 3rd unlockable building at the Construction Table and requires Explosive Salts and Forest Soul items to build it. Upon unlocking it, it will automatically start tracking your kills.

Death Note - Multikill and Damage Tiers

The Death Note is split into lists of mobs for each World. Each mob contributes towards that world's Multikill bonus.

Depending on how many kills you have of each mob, you'll gain a certain amount of points.

1 Point contributes 1% of Multikill for that World per Damage Tier.

Your Damage Tier is based on how much extra damage you deal to mobs. You can view this in the AFK Menu when on a map with mobs.

For example, if you had a Damage Tier of 35 on the Green Mushrooms map, you're Multikill Bonus for World 1 would be multiplied by x35!

Multikill then effects a mob's common drop resource; so if killing a Green Mushroom drops 1-3 Spore Caps per kill, and you have a Multikill bonus of 1000%, it will now drop 10-30 per kill.

Multikill is extremely important for increasing your Printer Sampling Sizes.

Your Multikill also contributes towards your Death Note Kill Count.
