In combat, attacks by weapon or by use of skills are resolved using an attack roll (Atk).
If the attack is physical (Atq PHY) whether it is in contact (Atk Melee) or at a ranged (Atk Ranged), the result of the test will be compared to the Physical Defense (Def PHY) of the opponent.
For magical attacks (Atk MAG), the test result will be compared to the opponent's Magic Defense (Def MAG).
A success can result in damage to enemies, tactical advantages, or other beneficial effects, while a failure can sometimes have harmful consequences for the characters.
Support type actions are not affected by combat tests, and are therefore automatically successful.
