Firebolt is a classic evocation cantrip in Dungeons & Dragons 5th Edition that delivers reliable ranged spell damage with straightforward scaling. Casting time is 1 action, range is 120 feet, and the spell forces a target to make a Dexterity saving throw or take fire damage. For players new to spellcasting or those evaluating consistent damage options, Firebolt offers a dependable baseline that remains relevant from 1st level through higher tiers when cantrips scale. This guide breaks down rules, level progression, class sources, and practical use cases for long‑term play.
Core Rules and Spell Text
Spell Level and School
Firebolt is an evocation cantrip included in the Player’s Handbook. It requires verbal and somatic components and has a range increment of 15 feet beyond the first 120 feet, making it notable for very long range. At base level it deals 1d10 fire damage on a failed Dexterity saving throw, and half damage on a success. Unlike some attack cantrips, Firebolt does not require concentration, which preserves flexibility for other abilities.
Attack Roll versus Saving Throw
Firebolt uses a saving throw DC rather than an attack roll, which changes how to-hit bonuses are calculated in practice. The DC is 8 + your proficiency bonus + your spellcasting modifier. This favors spellcasters with high spellcasting ability modifiers and benefits from meta magic or features that increase the DC. Range does not affect damage at 120 feet, but beyond that each 15‑foot increment imposes disadvantage on the saving throw unless features specify otherwise; many tables apply a progressive penalty to the DC or require an attack roll past point‑blank range.
Damage, Range, and Scaling
Cantrip Damage Progression
As a cantrip, Firebolt does not gain additional damage dice from level, but its relative damage scales as characters gain Hit Dice and average damage expectations rise. Furthermore, certain class features and magical items allow you to cast Firebolt using a spell slot, increasing damage to the appropriate slot level. This makes Firebolt efficient for resource‑conscious spellcasters who want consistent damage without expending higher‑level slots.
Long‑Range Implications
At 120 feet the spell is point‑blank; beyond that, many tables apply the rule that the target has cover for half the distance or that the spell’s accuracy suffers. This is a design cue to encourage tactical positioning. In practice, Firebolt remains reliable indoors or in narrow corridors where long range is less relevant, while outdoors it rewards careful line‑of‑sight management.
Class Sources and Availability
- Wizard: Spell known from level 1; can copy Firebolt into spellbook if not starting with it.
- Eldritch Knight (Fighter): Access through the War Magic feature and spellbook customization.
- Arcane Trickster (Rogue): Available via spellcasting feature and routine spell swaps.
- Sorcerer and Bard: Can select Firebolt as one of their initial cantrips, though many prefer other cantrips at higher tiers.
Practical Use in Play
Low‑Level Consistency
At low levels Firebolt provides steady damage that can rival or exceed a shortbow at a distance, without consuming limited spell slots. This makes it ideal for characters who need to poke from cover, soften enemies before melee engages, or handle small groups of weaker foes. Because it does not require concentration, you can maintain other buffs or defensive spells while firing.
High‑Level Context
At higher levels, Firebolt’s damage ceiling is often outpaced by leveled spell slots, yet its role persists as a slot‑saving tool and a reliable action in resource‑constrained situations. Some builds focus on pushing the DC with Ability Score Improvement timing, magic weapons, or items like the Staff of the Adder to gain extra damage dice when casting with a spell slot. In such cases, Firebolt becomes a flexible option for burning low‑level spell slots while preserving higher‑level resources.

Items, Metamagic, and Tactical Options
Magic Weapons and Enhancements
Certain magic weapons and implements, such as flame‑tipped arrows or staffs that allow spell‑like attacks, can synergize with Firebolt by adding elemental effects or altering range. While Firebolt itself cannot be metamagic‑adjusted in the core rules, home tables sometimes allow Empowered or Twinned variants with appropriate rulings; these should be confirmed with your DM.
Tactical Positioning
Because Firebolt has a long base range, it rewards positioning that keeps you in point‑blank while giving enemies cover penalties. Pairing Firebolt with features that grant additional movement or readied actions can create safe firing lanes. In environments with cover, consider using Dex saves and half‑damage results to preserve hit points while controlling enemy advances.
