Every two months, Everneth hosts a grand competition - an esteemed event where competitors are invited to prove their mettle in brutal combat. This event is known as Ultra Hardcore; a battle royale in which players are spread throughout a world of naturally-generated Minecraft terrain, and tasked with being the last player standing. But other contenders aren't their only challenge. In addition to the dangers inherent in the battlefield, natural health regeneration is disabled. Every wound suffered is a permanent scar, and the only way to regain lost health is by eating a golden apple, drinking a potion of healing, or killing another opponent and using the trophy dropped.
Additionally, each match - referred to as "seasons" - introduces a major twist to change up the game. Past scenarios include binding teammates health together, ores instantly being smelted, or advancements giving you a sliver of health as they're acquired. Sometimes, these twists become permanent; for instance, a shrinking border was introduced in an early season and has remained a staple ever since. No two seasons are ever alike, making the title of Champion that much sweeter.
A more detailed overview of the gamemode, as well as a hub for discussion, can be found on this forum post.
