Many various actions in the game cost one action token.
All of these actions are coupled to a formula to calculate the performance of your action.

Into these formulas, some of your character characteristics are used but the main formula’s vector is the result of a 100-faced dice roll.

The higher the result of the dice roll is, the better the performance of the action is.

When the result of the dice roll is lower or equal to 10, you find a summoning stone fragment that you need to collect to increase your summoner level.
