How to Increase Attack Bonuses?

Before we jump straight into the nitty-gritty of how you can increase attack bonuses, let’s establish a basic understanding.

How to Increase Attack Bonuses?

Your attack bonus in D&D 5E can sway the tide during your adventures, making it easier for your character to land successful hits on enemies.

This can be accomplished in a variety of ways, including adjusting ability scores and improving character proficiency.

Knowing how these mechanics work is key to mastering your gameplay. So, let’s break down some of the strategies you could utilize:

  • Boost Ability Score Modifier: Enhance your character’s relevant ability scores, such as Strength or Dexterity, whichever is more relevant depending on whether you’re engaged in melee or ranged combat. An increased score leads to a higher modifier, adding more value to your attack rolls.
  • Choose Dexterity or Strength: Your attack bonus is influenced by either your Strength (for melee attacks) or Dexterity (for ranged attacks). Therefore, choose wisely when distributing your level-up points.
  • Improve Ability Modifiers: As mentioned above, increasing ability scores will also improve modifiers linked with these abilities. These modifiers contribute directly to many aspects of gameplay, including attack rolls.
  • Ability Score Improvement: This is an option available at certain class levels that lets you increase one ability score by 2 points or two ability scores by one point each. This serves as another way to improve modifiers, thereby enhancing the overall attack bonus.
  • Feats for Ability Score: In some cases, selecting specific feats when leveling up instead of an Ability Score Improvement might prove beneficial as they may provide valuable bonuses on your attack rolls.
  • Magic Items for bonuses: Scattered around the D&D universe are various magical items that grant goodies, such as bonuses to attack and damage rolls. Getting hands on such magical artifacts could considerably bolster your prowess.

Remember that every choice you make while molding and growing your character will partly determine how well your character fares in combat. So strategize carefully, make informed decisions, and may luck favor you in your endeavors.

How do you find the Spell Attack Bonus for your class?

The spell attack bonus dynamic is unique for each class in D&D, depending on their specific spellcasting ability.

Each class uses a different attribute as their casting ability, which subsequently affects their spell attack bonus. Two classes under our lens today are the Artificer and Bard.


When we talk about Artificers, their driving force is intelligence. They base their spells on logical problem-solving and calculated measures, just as a real-life engineer or inventor would do.

To compute your Artificer Spell Attack Bonus, it’s crucial to keep track of two things – your Intelligence modifier and proficiency bonus.

Artificer Spell Attack Bonus = Intelligence modifier + proficiency bonus

Now, when you’re in a battle situation and need to roll for an attack using a spell, here’s the rule of thumb:

Attack rolls: Your d20 roll + spell attack bonus

The higher your Intelligence modifier and proficiency level as an Artificer, the better your chances of successfully impacting your opponents with spells.

Attack rolls: Your d20 roll + spell attack bonus

The higher your Wisdom, the stronger your connection to the divine force and, therefore, the more potent your spells.


Inextricably linked to nature, Druids cast their spells through an understanding of natural forces and wisdom. A Druid’s wisdom is key to their magical capabilities.

Here’s how you calculate it:
