Fireball 5e is a potent spell in Dungeons and Dragons. Every fireball caster should know how to use this spell properly. But, with great power comes great responsibility. Although it can completely obliterate an enemy in one shot, miscasting it or at the wrong target could have dire consequences on your party’s survivability. Here’s everything you need to know about fireball 5e so you can cast it right every time.

What is Fireball 5e?

Fireball 5e is a tabletop game where you are challenged to build and control a 5e party of adventurers. You must strategically fight against another player by casting spells and summoning monsters to help you along your quest. Fireball 5e was created in 2014 by two Canadian computer engineers in an attempt to take their favorite tabletop RPG - Dungeons & Dragons - into a more digital space, and it has taken off from there!

Character Creation

Fireball 5e can be played with as many or as few rules as you like. You’ll want to start by deciding your character’s race and class. Your race will affect your character’s abilities, strengths, and weaknesses; your class dictates how you train those skills. When it comes to fireball 5e, you have a few options for races—which include dwarves, elves, gnomes, half-elves, halflings, humans, and more—but only one choice when it comes to class (barring custom classes), which is a wizard. Besides these two things, there are very few limitations to what kind of character you can create. A big part of playing D&D is discovering your limits—so go ahead and take some risks!

Dice Rolls

There are a lot of dice rolls involved in fireball 5e, but don’t worry—it’s pretty easy to understand. Let’s break it down, step by step. Whenever you try something that includes an element of chance (including damage rolls), you must make a d20 roll. This is called an ability check or just a check, and it comes up quite often in RPGs. If you want to climb a wall or jump across a chasm, for example, your character needs to succeed on an ability check. If he fails his check, he can’t do what he wanted; if he succeeds on his check, he succeeds at what he was trying to do.


Fireballs set fire to combustibles and cause objects made primarily of wood to catch fire. A fireball spell throws a blazing sphere of fire into a random square within range. It ignites flammable objects in that square and causes 1d6 points of damage to creatures within 5 feet of it. (A creature in contact with burning flammable material takes 2d6 points of damage.) Combustible materials that are not worn or carried also take 1d6 points of damage if a ball of fire touches them. Fireballs do not affect cold-based creatures, but they inflict full damage against fire-based creatures regardless of whether those creatures have any vulnerability to fire.


Fireball is a level 3 spell, so it requires a high ability score (Intelligence or Charisma), preparation, and concentration. All three of these spells are damaged, so you might wonder what sets them apart. While all three are cantrips, fireball is considerably more destructive than its counterparts—but also much harder to pull off. While a magic missile’s main strength is that it can hit multiple targets, a fire ball’s main strength is that there’s no limit on how many times you can cast it. Because there’s no maximum number of fireball targets, each creature in the range must make a saving throw; if they fail, they’re saved and take full damage. On top of that disadvantage (fireball has a disadvantage on attack rolls), your opponents have an advantage on their saving throws because the fireball deals fire damage.

Leveling Up

A character who reaches the 5th level gains new spells and abilities—in particular, and they gain new spells per day as if they had also gained a level in whatever spellcasting class gave them access to 3rd-level spells at Level 4. If you’re playing with fireballs, here are a few recommendations for how to handle things when that happens. Fireball is a spell that can be used to attack or clear away obstacles. As an attack, it inflicts 1d6 points of fire damage per caster level (maximum 10d6) to all creatures within its area. As an obstacle remover, it explodes like a fireball cast by a 10th-level caster (maximum 20d6). Fireballs cannot remove physical barriers like walls or doors unless they are reduced to 0 hit points by their explosion; otherwise, they are merely pushed back by their force.

Sample Encounters and Bosses

Fireball 5e has much content you can pull from, but I’ll suggest a few specific encounters and bosses here. If you’re looking for more inspiration or need to pad out your adventure with a few more fights, feel free to include these in any order you like. The Cultists - A group of cultists surrounds their leader as he prepares to unleash his final spell against an adventurer party. These are level 2-3 cultists (as described on page 17) led by a wizard who casts a fireball at level 3 (as described on page 22). The Ratman King - A gnoll king is surrounded by several packs of gnolls and dire rats who fight for him.

Combat Examples

When you cast Fireball 5e, fire shoots from your outstretched hand toward one creature or object you can see within range. It explodes into a sphere of flames that spreads around corners and ignites flammable objects in its area. Each creature in a 40-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 fire damage on a failed to save or half as much damage on a successful one. At Higher Levels: When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d6 for each slot level above 5th.
