Melee weapons can strike adjacent foes, but ranged weapons cannot be used if the shooting character is engaged in melee combat. To make an attack, roll a d20 and add the character’s Strength or Wisdom bonus, depending on whether they are using a melee or ranged weapon, respectively. If the attack total is greater than the defender’s armor defense, the attack hits. If not, the attack misses.
Alternatively, an attack roll can also be resolved by the defender rolling a d20 and adding their armor bonus, hoping to roll a total greater than the defense of the ability the attacker is using. If they succeed, the attack misses. If they fail, the attack hits.
Designer's Note: In other words, attacks are resolved the same way as opposed saves, just using Armor in place of an ability.
On a hit, the attacker rolls their weapon’s damage die to determine how many Hit Points (HP) the defender loses. A bonus damage die of the weapon’s type may be added to the roll if the ideal weapon was used against an enemy type (for example, using a blunt weapon vs. a skeleton).
