Epic RPG: Boss battle mode
by HER0XP
Epic RPG: Boss battle mode changes how boss fights end by letting each defeated participant restore part of the boss's health, for servers that want harsher encounters.
What it does
Players who damage a boss are recorded in a participant list. When a participant dies during the fight, the boss recovers a share of its maximum health. When the final participant still standing falls, the boss regains its full maximum health; any other participant's death returns only a tenth of it. Some bosses can also heal players who die near them.
The mod is configurable, with a Dark Souls style mode and rules for who counts as a participant. Players must stay within 64 blocks of the boss by default, and leaving that range removes them from the list. A player who rejoins must deal damage to the boss again before counting as a participant. Because the mod is installed on the server only, players join without installing anything, and it is published for Forge and NeoForge with files for 1.20.1 and 1.21.1. The code is under All rights reserved, so it is not open source.
