Attacking With a Ranged or Melee Weapon
To find out if an attack hit:
Proficiency + Ability Modifier + d20 roll
Proficiency – depends on level, can be found at the top left of your character sheet or in the player’s handbook under your class’s page
Ability Modifier – If your weapon is melee, your modifier is likely strength. If your weapon is ranged, your modifier is likely dexterity. Finesse weapons such as daggers or monk weapons use dexterity. Hefty ranged weapons such as javelins and throwing axes use strength.
Damage With a Ranged or Melee Weapon
To determine damage:
Ability Modifier + d20 roll
Ability Modifier – use the same modifier (either dexterity or strength) that you used for attack hit.
