Template:Rules > Attacking and Defending

The Attack Roll

When making an Attack, you roll the following:

1d20 + Ability Score + Proficiency - Size Modifier

Ability Score

The Ability Score used in the Attack Roll depends on the type of Attack:

• For Weapon Attacks, the Ability Score is either Might or Agility. Might can be used for weapons with the Forceful tag and Agility can be used for weapons with the Finesse tag.
• For Spell Attacks, the Ability Score is the based on the Spellcasting feature of the class the spell comes from. For example, Masters of the Hidden Form use Wits to for their spell attacks, while Heralds use Resolve.

Proficiency

The Proficiency used in the Attack Roll depends on the type of Attack:

• For Weapon Attacks, you add Proficiency if you have the Combat Proficiency Feat.
• For Spell Attacks, you add Proficiency if you have at least one level in the class the spell comes from.

Size Modifier

The Size Modifier in the Attack Roll depends on the type of Attack:

• For Weapon Attacks, your Size affects how easy it is to hit your target. Your Size Modifier is subtracted from your roll.
• For Spell Attacks, Size has no effect on the Attack roll.

Result

The Attack roll total is compared to the target's corresponding Defense. If the roll equals or exceeds the Defense, the attack hits. Otherwise, the attack misses.

• For Weapon Attacks, you compare the roll to the target's Guard Defense.
• For Spell Attacks, the spell will specify what Defense is targeted by the attack.

Defending

When you are the target of an Attack, you must make a Defense roll using the following formula:

1d20 + Ability Score + Proficiency - Size Modifier

Ability Score

The Ability Score used in the Defense roll depends on the type of Attack:

• For Guard Defense rolls (usually from Weapon Attacks), you defend with Effective Agility. Your Agility may be reduced for Defense if you are burdened or wearing armor.
• For Might, Agility, Wits, and Resolve Defense rolls (usually from Spell Attacks), you add the associated Ability Score.

Proficiency

The Proficiency added to the Defense roll depends on the type of Attack:

• For Guard Defense rolls, you add Proficiency if you have the Combat Proficiency Feat.
• For Might, Agility, Wits, and Resolve, you add Proficiency if you have the associated Defense Proficiency Feat.

Size Modifier

The Size Modifier in the Defense roll depends on the type of Attack:

• For Guard and Agility Defense rolls, you subtract your Size Modifier from the roll.
• For Might Defense rolls, you add your Size Modifier to the roll.
• For Wits and Resolve Defense rolls, Size Modifier does not apply to the roll.
