Eclipse

Eclipse is an alternate gamemode that adds stacking challenge modifiers to successive runs. Each Survivor starts at Eclipse level 1, where Eclipse will have the first of the modifiers shown below. After successfully completing a run, that Survivor's Eclipse level will increment (up to a maximum of 8), and the next modifier will be added to future runs. Eclipse has the same difficulty settings as Monsoon, and Challenges that require Monsoon can be completed on Eclipse.

Note: "Ally" includes the survivor in all cases
 * 1) Ally Starting Health: -50%
 * 2) Teleporter Radius: -50%
 * 3) Ally Fall Damage: +100% and lethal
 * 4) Enemy Speed: +40%
 * 5) Ally Healing: -50%
 * 6) Enemy Gold Drops: -20%
 * 7) Enemy Cooldowns: -50%
 * 8) Allies receive permanent damage "You only celebrate in the light... because I allow it." (Note: uses the Permanent Curse Debuff)

Celestial Orbs do not spawn in this gamemode, nor can the artifact portal be spawned. Artifacts cannot be used in this gamemode. It can only be played solo.
