SCP-4910, The Grinner

The Grinner is a hostile mob that appears on the overworld surface at night, like a regular monster. Only one instance of SCP-4910 is allowed in a world at a time. It is agile and can leap toward players to overwhelm them in close combat, and it can break glass blocks, which makes it harder to contain. When it leaps, nearby players receive the Dentophonia effect, which drives them toward insanity.

The effect worsens across stages. Dentophobia brings weakness and nausea first, then severe damage, and a player who dies at stage 3 causes another SCP-4910 to spawn. Molar Serum, crafted from one bone meal, one sweet berries, one glass bottle and two sugar, removes the effect and stops the growth of teeth. The Grinner weakens when its health drops below 30, and it then flees and enters a rage mode, becoming even more dangerous.

Installation needs Geckolib. The mod runs on Forge only, with files for 1.19.2, 1.19.4 and 1.20.1, and the latest file is 1.0.0 for 1.20.1. It was created with MCreator. A server running it needs every connecting player to have it too. It is released under All rights reserved and is not open source.
