Combat Forecast is the small window that will appear before you can commit an action. From the same screen, you can see the following details:
* Might, projected Damage to the target
* Hit rate
* Critical rate
* Combatants’ remaining HP
* Allied units performing a Linked Attack
* Battalion endurance
From the same window, you can conveniently switch between different types of weapons, Combat Arts, and spells. The forecast will change accordingly. Once you're satisfied with the projected results, confirm your action for your unit to execute the attack.
