serost

Initial CurseForge release (1.0.0)

- One unkillable mob: Serost, the grey cat.
- 1-minute warning after joining the world, shown once per world and saved with it.
- Appears at the world spawn and hunts the player for the rest of the game.
- Knows the player's position at any distance, follows across dimensions, teleports to pillars, platforms, trees and walled-in players.
- Immune to all damage, /kill and the void; never despawns.
- Swims in water (including against the current) and floats on lava.
- Breaks doors, glass and wooden walls to get to the player.
- No name tag and no shadow — the kill message in chat tells you what happened.
- Client + server mod for Minecraft 26.3 / Fabric, requires Fabric API.
