Each unit has an ID. All IDs have 5 numbers, except for a few (See bottom).

1. The first number of the ID is determined by the unit's element. Fire units' ID start with 1. Water units' ID start with 2. Earth units' ID start with 3. Thunder 4, Light 5 & Dark 6.

2. The last number is determined by the number of stars the unit is.A 1-star unit will have 0 as the last number, 2-stars will have 1, 3-stars will have 2, 4-stars will have 3, 5-stars will have 4 & 6-stars will have 5.

3. Lastly, the global exclusive units (etc Xenon or Semira) have 6 numbers. The first number is always 8. The second number follows the same element rule as normal units. The difference is that the last number, instead of being 1 below the number of stars, is exactly the same. (etc Xenon is a 3 star dark unit, so its ID is 860003, whlist Lemia is also a 3 star unit, but its ID is 60162)

Sorry for the long wall of text, but hope this helps ^_^
