Improved Slings | Optional Rules for Dungeons & Dragons Fifth Edition

This one comes from Patron requests. Here’s what was asked:

My DM HATES slings. I’d love to have a way to use slings that doesn’t totally gimp my character.

Pretty weird that the guy would hate slings, but I understand weird hangups (I personally hate horses! Grrrr).

I thought about it for a minute and thought, why not expand upon the basic idea of slings?

Playtest Content

The material here is presented for playtesting and to spark your imagination. These game mechanics are in draft form, usable in your campaign but not refined by final game design and editing. They aren’t officially part of the game.

Constructive feedback is welcome and appreciated in either comments or social media. If you can give me a valid reason with examples why something is off, 9/10 I’m likely to make changes to the content and credit you for doing so. Otherwise, feedback without anything to back it up gets ignored (or at most a smile emoji like this 🙂 ) Thanks!

Design Notes

Here are my notes for this build.

Before the Build

So what do we know about the sling? Let’s break it down:

  • It’s a simple ranged weapon. And every single class can use it.
  • It costs 1 sp itself. Sling bullets cost 4 cp for 20.
  • A sling bullet deals 1d4 bludgeoning damage.
  • Slings use ammunition, of course, and have a range of 30/120.

In addition to the sling itself, there are a couple of feats that can buff it.

  • Crossbow expert lets you make attacks within 5 feet of a hostile creature without imposing a disadvantage to the roll.
  • Sharpshooter allows you to attack at long range without getting disadvantage, ignore half and three-quarters cover, and you can take a -5 penalty to the attack roll to add +10 damage to the attack.

Let’s take a look at the sling’s history. This comes from the site Rome Across Europe (bold emphasis mine in a few areas):

“A sling is a projectile weapon typically used to throw a blunt projectile such as a stone, clay, or glandes plumbeae (lead sling-bullet). Also known as the Shepherd’s Sling, this personalized weapon has a small cradle or pouch in the middle of 2 lengths of cord.

“The sling was inexpensive and easy to build. It has historically been used for hunting game and in combat.

“A classic sling is braided from a non-elastic material. The traditional materials are flax, hemp or wool; those of the Balearic Islands were said to be made from a type of rush.

“Flax and hemp resist rotting, but wool is softer and more comfortable. Braided cords were used in preference to twisted rope, as a braid resists twisting when stretched and thus improving accuracy.

“The overall length of a sling varied based on the range a slinger needed to hit, with a longer sling being used when greater range was required. An average sling would be about 2 to 3.28 ft in length.

“At the center of the sling was a cradle or pouch. This was either formed by making a wide braid from the same material as the cords or by inserting a piece of a different material such as leather.

“Typically diamond shaped, the cradle would fold around the projectile in use. Some cradles have a hole or slit that allows the material to wrap around the projectile slightly, thereby holding it more securely.

“At the end of one cord (called the retention cord), a finger-loop was formed, while at the end of the other cord (the release cord,) it was a common practice to form a knot or a tab. The release cord will be held between finger and thumb to be released at just the right moment.

“The simplest projectile was a stone, preferably well-rounded, and most likely from a river. The size of the projectiles varied dramatically, from pebbles massing no more than 1.8 oz to fist-sized stones massing 18 oz or more.

“Projectiles could also be purpose-made from clay, which allowed for very high consistency of size and shape to aid range and accuracy. Many examples have been found in the archaeological record.

The best ammunition was cast from lead (looking like an almond) which were widely used in the Greek and Roman world. For a given mass, lead, being very dense, offers the minimum size and therefore minimum air resistance.

“Why the almond shape was favored is not clear, but it may provide some aerodynamic advantage. Itś just as likely that the shape was easy to extract from a mold, or it would rest in a sling cradle with little danger of rolling out.

“Almond shaped leaden sling-bullets were typically about 1.4 inches long and about 0.79 inches wide, massing approximately 0.99 oz. Very often, symbols or writings were molded into lead sling-bullets.

“As a reminder of how a sling might strike without warning, examples of symbols included a stylised lightning bolt, a snake, and a scorpion. Writing might include the name of the owning military unit or commander or might be more imaginative: “Take this,” “Ouch,” and even “For Pompey’s backside” added insult to injury, whereas dexai (“take this” or “catch!”) was merely sarcastic.

“Julius Caesar writes in De bello Gallico, Book 5, about clay shot being heated before slinging, so that it might set light to thatch.

“A skillful throw requires just one rapid rotation. Some slingers would rotate the sling slowly once or twice to seat the projectile in the cradle.

“One made an overhand throw in a motion similar to [pitching a baseball]. This is relatively accurate, instinctive and quite powerful.

“Facing 60 degrees away from the target, with slinger stood with his non-throwing hand closest to the target. With the target at the 12 o’clock position, a right-handed thrower would orient his body toward 2 o’clock, with the arm rotating vertically in the 12 o’clock plane.

“The coordinated motion was to move every part of the body (legs, waist, shoulders, arms, elbows, and wrist) in the direction of the target in order to add as much speed as possible to the stone. The slinger released the projectile near the top of the swing, where the projectile would proceed roughly parallel to the surface of the earth.

“There were also sideways releases, in which the swing goes around. However, these throws made it very easy to release the projectile at a slightly wrong time and miss the target.

“Ancient peoples used the sling in combat. Armies included both specialist slingers and regular soldiers equipped with slings.

“As a weapon, the sling had the advantage of its bullet being lobbed in excess of 1,300 ft. A bow and arrow could also have been used to produce a long-range arcing trajectory, but ancient writers repeatedly stress the sling’s advantage of range.

“The Roman slingers would have exacted a heavy toll, for recent experiments conducted in Germany showed that a 50-gram Roman bullet hurled by a trained slinger has only slightly less stopping power than a .44 magnum cartridge fired from a handgun. Other tests revealed that a trained slinger could hit a target smaller than a human being from 130 yards away.”

Okay, wow. That’s a lot of cool shit. And it makes me wonder why slings got nerfed so much. I guess the game needed a cheap weapon that any dodo could use and “rope with rock” sounded like it hit the spot.

Right away, I know a few things that I want to do with this awesome weapon:

  • Rules for different types of ammunition for the sling. Probably “just a stone”, the clay bullet for versatility, and then the lead bullet. Maybe even mithril?
  • Possible magic that can improve a sling? Maybe a feat, or a new cantrip. I don’t feel like it needs an entire subclass, but maybe a magical feat that lets casters heat up stones with spells.
  • Feats that can make a sling what it’s really supposed to be: a long-range gun. That’s a tough area to work in since feats rarely ever raise DPS, and if it’s supposed to do .44-magnum damage, then its damage output would need to be 2d8 piercing plus Dex mod. That’s an effective increase of 6.5 damage or a 1d12.

Cool. This is exciting!

After the Build

I took a few cues from the Weapon Expert build I did not too long ago. First, I created some new sling bullets based on the historical information I listed above. The stone bullet was just a way to find cheap, free stones and gives some rules for such.

Because of the increased damage and range on the other two bullets, I had to make them martial weapons. Mithril’s cost is roughly 1/5 of what +1 ammo would cost as it only gives a +1 to attack rolls and not to damage and as ammunition, you’ll end up losing half of it every time you use it.

The two feats are no-brainers.

Because of the niche nature of sling master, I gave it a Dex bump. It increases critical damage by an extra die, but that’s barely a blip. Effectively, it’s an additional 0.275 damage per turn even with mithril, nothing to write home about. Also, I tossed in the martial proficiencies for wizards and sorcerers who plan on picking up this feat.

Arcane slinger allows a caster to learn a relevant cantrip, then cast it on sling stones. I changed acid splash’s ability a little, borrowing from oozes, but the rest are more or less the same. Some will be better with the sling (such as shocking grasp), while others which already have a pretty long range might suffer. That’s for the caster player to decide themselves.

Improved Slings

The optional rules in this article pertain to using slings in the game.

New Ammunition

In addition to the clay bullets normally offered in the PHB, a character has the following sling ammunition available to them.

Sling Bullets

Name Cost Weight Damage Range
Simple Ranged Weapons
Stone (20) * 3 lb. 1d4 bludgeoning 30/90
Clay (20) 4 cp 1 ½ lb. 1d4 bludgeoning 30/120
Martial Ranged Weapons
Lead (20) 5 sp 1 ¼ lb. 1d8 piercing 80/320
Mithril (20)† 75 gp 1 lb. 1d10 piercing 100/400

* Stone bullets are not purchased but found. While foraging outdoors near a river or similar body of water, a character can make a DC 10 Wisdom (Survival) check to find 20 stone bullets. Certain environments such as a natural cave or outdoors might also provide stones for the sling. These can be found with a successful Search action, DC 10 Wisdom (Perception).

† Due to the improved aerodynamic properties of mithril bullets, a character proficient with mithril bullets receives a +1 bonus to his or her attack roll on attacks made at normal range.

The table above replaces the normal statistics for a sling. A character proficient with slings can use both the stone and clay ammunition (clay ammunition is the standard ammunition detailed in the PHB). However, a character must be proficient with martial weapons or specifically with martial slings in order to use lead or mithril sling bullets.

New Feats

This section introduces a collection of special feats that allow you to improve the use of a sling. The feats are presented below in alphabetical order.

Arcane Slinger

Prerequisite: The ability to cast at least one spell

You have learned techniques to enhance your sling attacks with certain kinds of spells, gaining the following benefits:

  • You learn one of the following cantrips: acid splash, chill touch, fire bolt, ray of frost, or shocking grasp. Your spellcasting ability for this cantrip is Intelligence.
  • On each of your turns, you can use your bonus action to cast a cantrip you know selected from the list below on one of your sling bullets. If the next ranged attack roll you make using your sling hits, the bullet’s damage type is replaced as determined by the cantrip you cast upon it. Otherwise, the spell’s effect on the bullet ends at the end of your turn:
    • Acid splash. The sling bullet’s damage type becomes acid. In addition, nonmagical armor worn by the target is partly dissolved and takes a permanent and cumulative -1 penalty to the AC it offers. The armor is destroyed if the penalty reduces its AC to 10. The bullet’s damage increases by one damage die when you reach 5th level (2 damage dice), 11th level (3 damage dice), and 17th level (4 damage dice).
    • Chill touch. The sling bullet’s damage type becomes necrotic. If you hit an undead target, it also has disadvantage on attack rolls against you until the end of your next turn. The bullet’s damage increases by one damage die when you reach 5th level (2 damage dice), 11th level (3 damage dice), and 17th level (4 damage dice).
    • Fire bolt. The sling bullet’s damage type becomes fire. A flammable object hit by the bullet ignites if it isn’t being worn or carried. The bullet’s damage increases by one damage die when you reach 5th level (2 damage dice), 11th level (3 damage dice), and 17th level (4 damage dice).
    • Ray of frost. The sling bullet’s damage type becomes cold. In addition, the target’s speed is reduced by 10 feet until the start of your next turn. The bullet’s damage increases by one damage die when you reach 5th level (2 damage dice), 11th level (3 damage dice), and 17th level (4 damage dice).
    • Shocking Grasp. The sling bullet’s damage type becomes lightning. In addition, the target can’t take reactions until the start of its next turn. The bullet’s damage increases by one damage die when you reach 5th level (2 damage dice), 11th level (3 damage dice), and 17th level (4 damage dice).

Sling Master

You gain the following benefits:

  • Increase your Dexterity score by 1, to a maximum of 20.
  • You gain proficiency with martial slings.
  • You can roll one additional weapon damage die when determining the extra damage for a critical hit with a sling attack.  If you have a class feature or other effect that gives you additional weapon damage dice on a critical hit such as a Barbarian’s Brutal Critical feature, you add the dice together. For example, a 13th-level Barbarian that is a sling master rolls three additional weapon damage dice on a critical hit for a total of 4d4 (1d4 for the weapon x 2 + 1d4 for the Barbarian Brutal Critical Feature + 1d4 for this feat).

5 thoughts on “Improved Slings | Optional Rules for Dungeons & Dragons Fifth Edition

  1. The advanced ammunition is also roughly in line with the Magic Stone cantrip, which seems fine, though I’ve always found it puzzling that Magic Stone states that it can be used with a sling, although this doesn’t seem to confer any additional benefit over throwing the magicked stone barehanded.

    Thought One: would an Arcane Slinger with Magic Stone be able to gain the feat’s effects on Magic Stones launched from a sling? Should those effects live in the Stone (passable to another character), or just in the caster’s own hands?

    Thought two: should an “ordinary” Magic Stone behave any differently when launched from a sling?

    1. Interestingly, I forgot about magic stone when I was writing this. 1) I don’t see why not! And that might be a good idea there. 2) Since magic stone uses specifically a pebble, I think Magic Stone should just do its own thing. More or less another option for a slinger caster to have.

      1. The confusing thing about Magic Stone is that is written as a “ranged spell attack,” making using it with a sling very confusing. Do anything that boosts sling ability make the attack better? Or is the sling just where you can put a magic rock that does its own thing when you activate a spell.

  2. An interesting and well researched post, thanks for your work here. One small point, I would argue that Mithril is not the right metal for a sling bullet. Mithril’s main feature is making a weapon lighter, this would not matter much for arrows since most of their mass comes from the shaft, but for a sling stone it would as, obviously, less massive stones are going to have less energy. Adamant might be a better choice. Adamant could, theoretically, have the aerodynamic effects you are going for without losing weight. I suppose this could be solved by assuming that the mithril bullet is filled with lead. Adamant also adds a nice buff when breaking things.
    Another nice thing about sling bullets is they are easy to cast for special needs… silver bullet, no problem melt down some silver pour it into your handy cast, let it cool and you are ready to go.

  3. Two corrections for Sling Master, your example should be 5d4 for a 13th level barbarian as they get 2 brutal critical dice at level 13, though that is moot as the barbarian’s brutal critical only applies to melee attacks.
