Calculating Longbow Attack Bonuses

How to Calculate Longbow Attack Bonus in D&D

In D&D 5e, a character's attack bonus is the value added to a d20 roll when attacking enemies. This, along with the d20 roll, determines the character's chances of making successful attacks.

The basic formula for calculating a character's attack bonus is: Ability Modifier + Proficiency Bonus + Enchanted Item Bonus + Class Features.

When using a longbow, a type of ranged weapon, you will use your character's Dexterity (DEX) modifier for the ability modifier. You will add your proficiency bonus to this if your character is proficient with the weapon.

For example, if your ranger has a longbow with a +3 DEX modifier and a +4 proficiency bonus, their attack bonus would be +7.

A +2 enchanted longbow would also give your character a +2 bonus to attack rolls, bringing their attack bonus to +9.

Ranged weapons

When using a ranged weapon, your attack bonus is calculated by adding your Dexterity modifier to your proficiency bonus.

For example, if your ranger PC is wielding a longbow with a +3 Dexterity modifier and a +4 proficiency bonus, their attack bonus would be +7.

A +2 enchanted longbow would also give your PC a +2 bonus to attack rolls, bringing their attack bonus to +9.

If you are throwing a weapon, you can choose between using your Strength or Dexterity modifier, depending on the weapon. Thrown weapons include hand axes and daggers.

Thrown weapons

Firstly, it's important to understand what is meant by an attack bonus. In D&D 5e, an attack bonus is the value added to a d20 roll when making attacks. This, along with the d20 roll, determines your character's chances of successfully attacking enemies in combat.

When it comes to thrown weapons, the formula for calculating the attack bonus is similar to that of melee weapons. For most thrown weapons, the formula is: Strength Modifier + Proficiency. However, if you are throwing a finesse weapon, you have the option to choose between using your character's Dexterity or Strength Modifier instead. Generally, it is best to use whichever ability modifier is higher.

For example, if your character throws a hand axe, the formula would be STR + Proficiency. On the other hand, if your character throws a dagger (a finesse weapon), you could choose between DEX + Proficiency or STR + Proficiency, depending on which modifier is higher.

It is worth noting that proficiency plays a crucial role in determining the attack bonus. Proficiency bonus increases as your character levels up, and it is added to ability checks, attack rolls, and saving throws that your character is proficient in. Therefore, it is beneficial to ensure your character is proficient with the weapons they are using, as this will increase their chances of successfully landing attacks.

Additionally, there are other factors that can influence the attack bonus for thrown weapons. These include class features, magic weapons, and spells, which can provide additional bonuses to attack rolls.

Melee weapons with the finesse property

When using a melee weapon with the finesse property, you can use your Dexterity modifier to determine your attack bonus instead of your Strength modifier. This means that you use your Dexterity modifier for both the attack and damage rolls.

Finesse weapons are typically favoured by Dex-based characters like Rogues. They are lighter and rely on precision and agility. This includes rapiers, daggers, scimitars, and shortswords.

For example, say you equip your rogue PC with a rapier. If your PC has a +5 DEX modifier and a +3 proficiency bonus, their attack bonus would be +8 (5 + 3).

Then, say a fellow PC used a class feature like Bardic Inspiration to give your rogue another +2 bonus to their attack roll. Their attack bonus would be +10 (5 + 3 + 2).

Melee weapons with proficiency

When using a melee weapon, the attack bonus formula is: Strength Modifier + Proficiency Bonus. If you have proficiency in the weapon, you can add your proficiency bonus to the attack roll.

For example, if you have a +4 Strength modifier and a +2 proficiency bonus, your attack bonus would be +6.

If you are using a finesse weapon, you can choose to use your Dexterity modifier instead of your Strength modifier.

Melee weapons are any weapons used to attack an enemy within 5 feet of you, such as swords, maces, and clubs.

Your proficiency in a weapon is determined by your race, class, and feats. Most people are proficient with simple weapons, which include clubs, maces, and other weapons commonly found in the hands of commoners. Martial weapons, such as swords, axes, and polearms, require more specialized training and are typically used by warriors.

You can increase your attack bonus by boosting your ability modifier or proficiency bonus. You can increase your ability modifier by levelling up or finding ability-boosting items, gear, and tomes. Your proficiency bonus will automatically increase as you level up.

Additionally, you can find enchanted weapons that grant a bonus to attack rolls. These bonuses typically range from +1 to +3. For example, if you have a +1 enchanted weapon, your new attack bonus would be +7 (4 + 2 + 1).

Spellcasting attack bonuses

To calculate your spell attack bonus, add your spellcasting ability modifier to your proficiency bonus.

Your spellcasting ability is determined by your character class and is the ability your character uses to power their spells. For example, a wizard uses Intelligence, so their spellcasting ability modifier is their Intelligence modifier.

Your proficiency bonus is based on your character's level.

So, for example, a level 1 Warlock with a Charisma of 15 (a modifier of +2) and a proficiency bonus of +2 would have a spell attack bonus of +4.
