Apocalypse

Apocalypse is a difficulty modifier in Battle Arena which is enabled by equipping both the Invisible X Invisible Ally and the Worst Moon Gem (equipping only one of the two enables Worst Moon instead). Apocalypse is indicated by a darkening of the current room and the appearance of a red moon in the upper-right corner.
Apocalypse's effects are qualitatively similar to Worst Moon's effects; however, the changes effected by Worst Moon are compounded further by the changes effected by Apocalypse. Since Apocalypse's changes are applied on top of Worst Moon's changes, this article only gives the additional effects caused by switching from Worst Moon to Apocalypse.
