During the promotion, a multiplier would be in effect which will increase the rewards from Treasure Hunter. The multiplier is re-rolled for each opened chest, and starts with only the single reward option available. The cap of the multiplier can be increased by 1 to a maximum of 7 by claiming a multiplier unlock (which is also available on Treasure Hunter). All prizes won on Treasure Hunter are multiplied by the multiplier when a key is used, except multipliers themselves.
