True Ending Data Pack Wiki & Guide

The reworked multi-phase Ender Dragon fight, its new attacks, and the cinematic true ending.
Overview
True Ending is a boss and story overhaul that reinvents the Ender Dragon fight and gives the game a proper, cinematic conclusion. It rebuilds the encounter into a long, multi-phase battle that keeps escalating as you lower the dragon's health, then rewards you with a real, story-driven finale instead of the usual end poem. Everything is data-driven, so you progress to the End as normal and get the upgraded fight and ending on top of your existing world.
