Crystal boxes
There are two types of Crystal Boxes: a common variant that drops regularly as the battle fund increases, and a unique super-variant called the "Gold Box," which is essentially a regular Crystal box but has a much smaller chance of dropping as the battle progresses.
Regular Crystal drops
Crystal Boxes are a specific type of bonus box that may appear at any time in a blue color and at an undetermined location. This box rewards the player with 10 Crystals upon capture.

Gold box
A Gold Box is a super-variant of a regular Crystal Box, which rewards the player who captures it with 1000 Crystals. These boxes are dropped at random during the battle, with a 1 in 7000 chance for every added battle fund triggering one of these unique boxes.
Upon the notification stating "Gold Box will be dropped soon," one of the special boxes will spawn at a random location on the map after a period of 40 seconds has passed.
