Weapons - Choosing Equipment

Player's Handbook, D&D Basic Rules, D&D Player's Basic Rules, Essentials Kit Rulebook

For each weapon your character wields, calculate the modifier you use when you attack with the weapon and the damage you deal when you hit.

When you make an attack with a weapon, you roll a D20 and add your proficiency bonus (but only if you are proficient with the weapon) and the appropriate ability modifier.

• For attacks with melee weapons, use your Strength modifier for attack and damage rolls. A weapon that has the finesse property, such as a rapier, can use your Dexterity modifier instead.
• For attacks with ranged weapons, use your Dexterity modifier for attack and damage rolls. A weapon that has the thrown property, such as a handaxe, can use your Strength modifier instead.
