  • The orb color distribution table displays the chances for a certain orb color to appear.
    • Individual: The chance for a randomly selected orb to be a certain color.
    • All: The chance for all orbs to be a certain color.
    • At least one: Chance for at least one of this orb color to show up in a summoning session.
    • None: Chance for no orbs of this color to show up in a summoning session.
  • The specific Hero rates table shows the chances for specific Heroes.
    • Appearance rate: Individual Hero appearance rate. This is the chance for a randomly selected orb to contain the Hero. This includes all non-focus rarities of the Hero as well in addition to focus rarities. This rate × 5 is the chance for the Hero to show up at all in one of the 5 orbs in a summoning session.
    • Rate | Orb color: The chance to summon a specific Hero given that their orb color has appeared and is being summoned from. This is dependent on color distribution of units in all the pools. This includes all non-focus rarities of the Hero as well in addition to focus rarities.


The following table documents the results of a simulation where 10,000 simulations are run per focus unit. In each simulation, an AI plays optimally and tries to summon a specific focus unit using the least amount of orbs possible. The method of play is described below:

  • Summon from only from the colored orbs that are the same color as the targeted unit.
  • If no such orb exists in a session, summon from the color that has the smallest chance to summon a 5★ Hero, then exit that session.
