About this project
What does Merl Effect add?
MerlEffect enhances your gameplay by adding an all-new effect called 'merl' that you can inject upon yourself. Upon recieving the effect, all of the text in the game (excluding dynamic text, such as chat messages) will turn into 'I don't know' as shown below:

A Merl potion is brewed using a nether star. When applied, it magically turns your brain into Merl's!
Currently supports 1.21.11. If you would like to request a version, please do so on my Github - I'll get on it right away!
