What are all the ways to change my attack roll's ability modifier?

Question

Hexblade Warlock has this line in it:

When you attack with that weapon, you can use your Charisma modifier, instead of Strength or Dexterity, for the attack and damage rolls.

Battle Smith Artificer has this line in it:

When you attack with a magic weapon, you can use your Intelligence modifier, instead of Strength or Dexterity modifier, for the attack and damage rolls.

These two are the only examples of this I've found. I might be missing something, though.

I tried to google search "dnd change attack roll modifier" but all I got were noob questions like this, this, or basic/universal information like this. Yes, I understand that normally attack rolls are dice + proficiency bonus + STR or DEX. I'm asking about all the ways to change that ability modifier (like the two subclasses I listed above).

I looked at a few Cleric and Paladin subclasses and only found Oath of Devotion's Channel Divinity (lets you use STR/DEX and CHA on rolls).

Answer 1

Here is a list for all the different ability scores. It overlaps with this list for ways to use something other than Dexterity or Strength, but covers those two, too.

Strength

• As your ranged attacks (except for those with thrown weapons) usually use Dexterity, it might be desirable to use Strength instead of Dexterity for non-thrown ranged attacks Strength based characters. However, there seem to be no features enabling this.

Dexterity

• Finesse weapon. Any weapon with the finesse property allows you to use your Dexterity modifier instead of Strength. This works for any class, and is often used with classes like Rogue or Bard.

• Monk 1 for unarmed strikes or monk weapons, or Kensei Monk 3 from Xanathar's Guide to Everything for your Kensei weapons allows you to attack with Dexterity instead of Strength.

Constitution

• Damphir Lineage (Van Richten's Guide to Ravenloft): Vampiric Bite feature allows you to add your Constitution modifier instead of Strength with the bite.

Intelligence

• Artificer Battle Smith 3 (Tasha's Cauldron of Everything): Battle Ready feature allows you to use your Intelligence modifier instead of Strength or Dexterity, when attacking with a magic weapon.

Wisdom

• Druid 1: The shillelagh cantrip allows you to use your spellcasting ability, Wisdom as a druid, instead of Strength. (Likewise, feats that let you pick up the cantrip, such as Magic Initiate). Duration one minute on club or staff.

• Way of the Astral Self Monk 3 (Tasha's Cauldron of Everything): Arms of the Astral Self feature allows you to attack using Wisdom modifier instead of Strength or Dexterity with your astral arms.

Charisma

• Hexblade Warlock 1 (Xanathar's Guide to Everything): Hex Warrior feature that allows you to attack with your Charisma modifier instead of Dexterity or Strength. Works only with your pact weapon.
• Bard 6: A College of Lore Bard can use Magical Secrets to get the shillelagh as a bard spell, and as their spellcasting ability modifier is Charisma, use it with Charisma. (Any bard can do that at level 10, too).

P.S. Oath of Devotion says:

As an action, you can imbue one weapon that you are holding with positive energy, using your Channel Divinity. For 1 minute, you add your Charisma modifier to attack rolls made with that weapon

As you correctly observe, it is not changing your ability bonus for those attacks, it is adding Charisma to whatever other bonuses those attacks may have. So, if you attacked with a melee weapon using your Strength ability bonus, you now would add both your Strength and Charisma bonuses to those attacks to hit with that weapon.

There may be other ways that allow you to somehow enhance your attacks with other ability bonuses. I only covered changing the bonus to another in this answer.
