Invoker stars: rates per pull

Item	Common	Uncommon	Rare	Epic	Legendary
Wild Star	70%	28.5%	1.5%	–	–
Fate Star	–	–	91.67%	8.33%	–
Destiny Star	–	–	91.14%	8.33%	0.53%
Radiant Star	–	–	91.14%	8.33%	0.53%
Divine Star	–	–	–	93.33%	6.67%

Wild Star Uncommon is 25.65% Fire, Water, Earth and Wind plus 2.85% Light and Dark. Radiant Stars only give Light and Dark heroes. Every hero in a rarity is equally likely, so one specific Destiny Star Legendary is 0.53% ÷ 38 heroes, about 1 in 7,170 pulls; from a Radiant Star it is about 1 in 3,585.

Chance of at least one Legendary

From the rates alone, with no mercy and no bonus summons.

Mercy

Pulling that rarity naturally resets its mercy count, so you only reach mercy after a long dry run. "Reach mercy" is how often that happens; "Rate with mercy" is the long-run chance per pull once mercy is counted, next to the listed rate.

Not yet known: whether items share a mercy count. The calculator uses 30 for Epic mercy, the safe end of the range.

Bonus summons

Using summon items fills bonus counters that pay out extra summons. These never reset, so every player gets one on every count, whatever they pull.

Chroma chance

Any pull can come out as a chroma (alternate colour) version.
