The Moon - Upright
Embrace the shadows completely. Perpetual night vision pierces darkness. Each nightfall grants 10 minutes of Speed II. At night, hostile mobs lose track of you (30% chance every 4 seconds). The moon blesses its children.
The Moon - Reversed
Harsh daylight overwhelms your senses. During daytime, 5% chance every 5 seconds to suffer 5 seconds of Blindness as clarity obscures truth.
