Attack Roll

Entities make an Attack Roll when they attempt to attack a target.

If the result of the roll is higher or equal to the target's Armor Class (AC), the attack succeeds. Depending on the attack, the attacker can then roll for damage, unless an immunity or other effect prevents them from doing so. If the result of the roll is instead lower than the target's AC, the attack fails.

If an entity has no Armor Class, Attack Rolls against it immediatly succeeds.

Critical Hits & Critical Misses

When an entity lands a Critical Success, their attack usually turns into a Critical Hit.

Upon landing a critical hit, the attacker rolls twice the amount of base dice on a Damage Roll. Modifiers are not doubled.

When an entity lands a Critical Failure, their attack completely misses their target.

Armor Class

Armor Class is a number unique to an entity, measuring how difficult it is to hit them. To successfully hit them with full force, the attack must be equal to or greater than the target's Armor Class. AC can be modified by many sources, like equipping shields, armor, using certain spells, or increasing finesse related Abilities.

The following formula determines AC when using an Idiom :

Armor Class = Armor + Signature Modifier + Shield Bonus + other bonuses and penalties

When wearing no armor, the armor value becomes 10.

The Signature Modifier is the Modifier of the Ability called Signature, a global indicator of an entity's finesse and fortune.
