Touch of Elune

Touch of Elune is a passive night elf racial trait with the unique property of giving a buff to Haste or Critical Strike depending on the time of day, benefiting all playable classes to some degree. Notably, it is the only known racial to apply different alternating benefits to players between the night and day.

Trivia

 * This ability seems to be granted to night elves by the power of their moon goddess Elune.
 * As all instances are set to 'daylight hours', night elf characters are guaranteed the Crit bonus no matter what time it is.
