The following page lists all the available chess pieces together with their species and class. For effects of the latter, see their respective pages.

Chess pool[edit | edit source]

Chess pool is shared for all chess players. Each different piece has its own unique pool according to its cost:

Chess Cost Chess Pool Size
1 45
2 30
3 25
4 15
5 10

When a 1/2/3 star unit return to the pieces pool (sold/player die), 1/3/9 1 star pieces of that unit are added to the pool. If the unit is a Druid, 1/2/4 units are added instead.

Because of this, it is possible to reduce the overall total number of Druid pieces in a game if combined using 3 pieces.

With the introduction of Io (see in later section), it is possible to return more pieces than required to combine, which can increase overall total number of any piece in a game.

Chance to roll[edit | edit source]

The chance of rolling rarer pieces is linked to your level. You can see the percentages in-game by selecting your courier and hovering over the tower/reroll icon on your skill bar.

SSR pieces and IO[edit | edit source]

SSR pieces are alternative versions of some chess pieces that are much more powerful than their normal counterparts.

They have stats comparable to 3 star units and cannot be upgraded. They have different abilities from their normal counterparts.

Known SSR versions exist for Chaos Knight, Necrophos.

Io is a 5 cost piece that can be used as a substitute in place of other chess piece for upgrading.

SSR pieces and Io do not belong to the piece pool and theoretically there are infinitely many of them. When sold, they also do not return to the normal piece pool.

Rolling mechanics[edit | edit source]

For each slot of the Reroll interface, roll 2 random numbers in range 1 to 10000.

  • If both rolled 1 and courier level is 7 or more, that slot offers a random SSR piece.
  • If above check fail, and if the first random number rolled 30 or less, that slot offers an Io.

Rolling chance[edit | edit source]

Effectively, the chance for a slot to offer a SSR piece is 1 in 100,000,000 or 0.000001%, provided that your courier is level 7 or more.

The chance for a slot to offer an Io is 30 in 10,000 or 0.3% (minus the minuscule chance for SSR piece). (This check has no courier level requirement.)
