Rare SummonEdit

Even though it's called a rare summon, the game itself revolves around getting strong rare summon units to defeat stronger foes.

No more troll rainbow crystal after gacha change

Whenever there are more than one featured unit of the same rarity, the chance is split evenly among them. Off-banner unit are also split evenly among remaining non-featured units. This kind of split is called a normalized pull, where one unit is not preferred over another. Normalized pull was introduced to the game without any notice starting from the first FFXIII banner in December 2, 2016.

While rare summon units have several rarities available for awakening, their base rarities differs from one to another. Rare summon unit can only be summoned from their base rarities. For example, if you happen to summon a 5-star unit from a rainbow crystal, that unit will be a base 5-star. This change, commonly called gacha change, happens after the update to version 2.0.0 in February 23, 2017.

Originally, the rainbow rate was 1%, 0.5% for both off-banner and featured, but it was changed to be 2% for off-banner and 1% for featured for a total of 3%. Rainbow rate was tripled in November 24, 2017.

Based on the visible summon rate on the JP version, these are the chances to pull rare summon unit of the following rarities. Note that while Gumi currently publishes the rates for rarity of drops (i.e. Blue, Gold or Rainbow), they do not publish the rates for on-banner and off-banner pulls. Surveys have experimentally shown these rates to be roughly consistent with the rates in JP.

Rare Summon Rate
Rarity	Crystal	Featured Unit	Off-banner Unit	Total
3-star	Blue	20%	58%	78%
4-star	Gold	4.75%	14.25%	19%
5-star	Rainbow	1%	2%	3%

4★+ Guaranteed SummonEdit

You can increase the summoning rate by using a multi-summon for 5,000 or by using a 4★+ Guaranteed Ticket, given from various event and promotion. In case of the multi-summon, only the first summon has an increased rate, while the rest are using the rate seen above.

Based on surveys for 4★+ Guaranteed Summon, featured gold crystal is at half rate from the published rates for JP. However, this has been updated along with rainbow rates in November 24, 2017 to match with the rate on JP

Guaranteed Summon Rate
Rarity	Crystal	Featured Unit	Off-banner Unit	Total
4-star	Gold	47.5%	47.5%	95%
5-star	Rainbow	3.75%	1.25%	5%

Crystal UpgradeEdit

Animation difference: Gold crystal on the left will upgrade into a rainbow crystal while the one on the right will not

Crystal might upgrade to a higher rarity during summoning. However, this is just a cosmetic, and does not impact the summoning rate at all. Even before cracking the crystal open, the unit have been summoned by the game.

There is a small difference in animation when a gold crystal will upgrade into a rainbow crystal. The amount of rays emitted from the crystal before breaking are much less, about half of the usual amount, not enough to cover most of the screen. This difference is only applicable to gold crystal upgrade, and there is no discernable sign when a blue crystal will upgrade.
