Lightning Bolt 5e Advantages and drawbacks


  • High damage: The Lightning Bolt spell deals a lot of damage, dealing 8d6 lightning damage on a failed to save or half as much damage on a successful one.
  • Long range: When this spell is cast, it forms a line 100 feet long and 5 feet wide that blasts out from the spellcaster in a direction they choose, giving a long enough distance to fight against multiple enemies found.
  • Targetable AoE (Area of Effect): Given that you can choose a target for this spell, it’s a great way to avoid hurting your fellow party members. In addition, creatures within 5 feet of the point will take damage as well!
  • Guaranteed damage: Regardless of whether or not the enemy passes the Dexterity saving throw, it is ensured that they will receive tremendous damage with this spell. If they succeed, they will still have to receive half of an 8d6 damage roll. 
  • Upcast: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot above 3rd.
  • Casting time: Unlike many other spells that require concentration, the Lightning Bolt spell only requires one action.
  • Special feature: A feature of the Lightning spell is that the lightning ignites flammable objects in the area that aren’t worn or carried, which can be useful in creating clearings. This applies when you want to fire your enemies’ hideouts, evil lairs, and so on.
  • Spellcaster safety: Since the Lightning Bolt spell is blasted out from the caster, this prevents the user from being harmed by the spell.


  • Instantaneous: The Lightning Bolt spell can only last at the instant it has been cast and doesn’t last for a longer duration than that.
  • Common saving throw: The problem with this spell is that it requires a Dexterity saving throw by the target. Many monsters in Dungeons and Dragons can be found with a saving throw proficiency in this, dealing only half of the damage.
  • Common damage type: Out of the plethora of creatures found in Dungeons and Dragons, many of them can be found to have resistances and even immunities to lightning.
  • Needs components: This spell requires all three spell components: bodily, verbal, and materials. Since it requires materials to cast, it means if you don’t own the materials, lose them or even have your materials taken away from you, you will be unable to cast this spell. What’s more, with the requirement of a somatic and verbal component, if you are in a situation where you are unable to move and are muffled, this also hinders you from casting. 
  • A disadvantage to your party: During combat, your party members who are along the line of the range will be affected by the spell and will receive damage whether or not they pass the saving throw.
  • Fire hazard: An issue of the Lightning Bolt spell is the potential destruction around the surrounding area. As the spell describes, “The lightning ignites flammable objects in the area that aren’t being worn or carried.” So, one must be careful of using this spell around wooden houses, trees, indoor areas, and so on that one may want to avoid setting on fire.

Lightning Bolt FAQ

Should I choose Fireball or Lightning Bolt for my next spell?

Though the Fireball spell and the Lightning Bolt spell feature some similarities like long-range, ignition of flammable objects in the area, damage die, and such, Lightning Bolt is the safer option. Unlike the Fireball spell, where a 20-foot-radius sphere is centered on a targetted point, causing AoE damage, with Lightning Bolt, the spellcaster has better control of who they may target. The Fireball spell can be quite destructive to allies without proper planning. All in all, it is best and easier to use the Lightning Bolt spell.

Do the targets in front of the Lightning Bolt spell provide half cover for the line? 

Technically yes, because according to the 5th Edition System Reference Document, 
“A target with half cover has a +2 bonus to AC and Dexterity saving throws. A target has half cover if an obstacle blocks at least half of its body. For example, the obstacle might be a low wall, a large piece of furniture, a narrow tree trunk, or a creature, whether that creature is an enemy or a friend.”
This means that enemy targets can be shielded by any targets in front of it, granting them half cover.

Is there a way to increase the range of Lightning Bolt? 

No, a spellcaster cannot increase the range of the Lightning Bolt spell since there is no mechanic in Dungeons & Dragons 5th Edition available.

Can you use the Lightning Bolt spell underwater?

Yes, you can. This is because the spell’s damage dealt is considered to be magical. Thus, the spell deals magical lightning damage, and the spell’s description does not say otherwise; a spellcaster may be able to use this spell. But it may be advisable to consult your Dungeon Master if this is an acceptable way to use this spell.

Does the Lightening Bolt spell cause extra damage to creatures in water?

Spells with lightning damage, such as the Lightning Bolt spell, do not behave differently in water since the spell’s description does not state any interaction between it and water.
