  • unit - A unit to query (string, unitID)
  • index - Index of a buff or debuff on the unit (number)
  • filter - A list of filters to use when resolving the index, separated by the pipe '|' character; e.g. "CANCELABLE|PLAYER" will query cancelable debuffs cast by the player (string)
    • CANCELABLE - Show auras that can be cancelled
    • NOT_CANCELABLE - Show auras that cannot be cancelled
    • PLAYER - Show auras the player has cast
