POWER is a factor of the dice's level and star count. The higher the POWER the mightier your dice.
The combined POWER values of your active dice team is compared to the level difficulty and it determines three of the most important aspects to complete a level:
  1. Your "Critical Hit Chance”,
  2. How much damage each Shield you roll is able to block, and
  3. How much damage you can take from enemies before you die.
A higher “Critical Hit Chance” means that there is a higher probability to get an extra attack with any sword rolled. The percentage is displayed left of the health bar. The exact amount of damage blocked by each rolled Shield is shown to the right of the health bar. Enemies get tougher in later levels, so keep leveling up your dice!

Patrols also have a POWER requirement. You can only start a patrol if the assigned dice meet the requirement.
