One Tap Phantoms
This mod allows you to configure the health of Phantoms in Minecraft. In the standard version of the game, these flying creatures have 20 health points - the same as the player. Many believe this makes them too tanky for such annoying mobs. By default, the mod sets Phantom health to 1 point, allowing you to eliminate them with a single hit. However, you can change this parameter to any value you prefer. For example, setting health to 10 points means you'll only be able to one-shot Phantoms with a diamond sword enchanted with "Sharpness V".

Configuration
You can configure the mod in two ways: directly in the game or by editing the JSON file config/onetapphantoms.json in your profile folder.
phantom_hp — parameter that determines the amount of health with which Phantoms spawn
