Welcome to Cube UHC Season 19!
In UHC mode, health does not automatically regenerate, so players must use a golden apple or golden head.
In this season of UHC, we have 12 participants scattered across a 1500x1500 map with a shrinking border where CutClean, Perma Night and Custom Terrain is enabled; ores are smelted automatically and netherrack turns into cobblestone.
Plugins and hosting provided by LearningMonkey (mc.thecoa.st). Intro created by FinsGraphics (http://www.youtube.com/FinsGraphics).
