1% chance to execute an enemy. Performing Execute increases Damage by 1%.

Joe's Dagger Megabonk – Explained

Executes instantly kills any non-boss enemy and gives you +1% damage (with 1 copy).
 
For bosses and red ghosts, executes deals 2% of their max HP.
 
For bosses specifically, when an execute triggers you do not gain the +1% damage bonus. This is only true for boss-type enemies.
 
You can max get the damage bonus from executing every 0.3 seconds (even if you execute more frequently than that with high attack speed)
 
Any executes (regardless if they came from Joe's dagger or other sources like the dexecutioner) will give you the damage bonus if you have Joe's dagger.
 

Note that under normal conditions you can MAX get 10 copies of Joe's Dagger in-game.

 
You can however get more anyway with a lucky shady guy. The items the shady guys sells are determined as soon as you enter the stage, and they can have a Joe's Dagger. If you get a 10th dagger from chests, the shady guys that spawned in will still be able to sell you an extra copy, although you theoretically are over the limit.
 
You may also be able to get another one with microwave shenniangens (although if you try to microwave one after getting 10, you will get an error message). But you are able to leave one in the microwave and come back later after getting more than 10 to pick it up.

How it Stacks

Let $n$ be the number of Joe’s Daggers.
 

1) Execute proc chance

- 1%, regardless of how many daggers you have.
 

2) Damage gained per proc (scales with copies)

The Damage gained per proc is set from:
 
 
$$\Delta\text{Damage}(n)=0.01n$$
 
 
Examples:
- 1 dagger → +1% Damage per proc
- 10 daggers → +10% Damage per proc
 

3) Proc credit cooldown (rate limit)

Proc credit is rate-limited by rollCooldown = 0.3s:
 
This means that even if your execute triggers multiple times during a 0.3s window, you will only get the damage buff once, so: You can gain the permanent Damage bonus at most once every 0.3s (even if you hit faster).

    Does this work with the dexecutioner? it says when performing an execute but, is it treated like a separate execution that wouldn't up your damage ?
    Reply from IndieSnek:
    Good question! All executes are treated the same in the code. I'll update the article to reflect this So yes, executes from dexecutioner will also up your damage if you have a joes dagger
