Discover the Best Demolition Expert Build in Fallout 4 and how to create a powerful character with Perks, S.P.E.C.I.A.L., Stats, armor, and weapons.
This build guide has been updated for Game version 1.10.980 on PC and Free Next Gen Update on PlayStation and Xbox.
Best Demolition Expert Build in Fallout 4
The demolition expert build is powerful and versatile, using explosives to destroy enemies and obstacles. What makes the Demolition Expert build unique are weapon perks that stack and add multiple damage amplifications simultaneously. You can use Spray n’ Pray and gain the benefits of Commando, Demolition Expert, and Bloody Mess! Thus, you have one of the highest damage-producing weapons due to multiple perks adding to the overall weapon’s damage rather than one. Moreover, you will have various weapons and grenade choices in the Wasteland.
The downside of the build is friendly fire, which you can damage yourself with explosives. However, we will take defensive and survivability perks to protect against explosives. Moreover, you forgo Intelligence SPECIAL stat, so don’t expect to have every crafting perk unlocked at level 50. However, if you enjoy watching things go “boom,” the Demolition Expert build is for you!

The best S.P.E.C.I.A.L. stats for the Demolition Expert build are 7 strength and 7 endurance. Strength is necessary because it contains Heavy Gunner, Armorer, and Steady Aim perks. These will help you with larger weapons, hip fire accuracy, and carrying more materials. Endurance is vital for survivability perks like Adamantium Skeleton, Life Giver, and Toughness. Intelligence contains medic and gun nuts that are useful for survivability and crafting. Agility has Commando, which is excellent for automatic weapons. Lastly, Luck has Bloody Mess, useful for a flat increase in damage and explosive kills.
Below are the best recommended S.P.E.C.I.A.L. Stats for the Demolition Expert build in Fallout 4 videogame RPG:
- 7 Strength (S): influences your carrying capacity, melee damage, and the effectiveness of melee weapons.
- 5 Perception (P): affects your accuracy in VATS, the chance of detecting stealthy enemies, and the ability to pick locks and spot traps.
- 7 Endurance (E): It affects your maximum health, radiation resistance, and ability to withstand environmental hazards.
- 1 Charisma (C): influences your success in dialogue options, ability to negotiate prices with vendors, and effectiveness in leading companions.
- 3 Intelligence (I): affects the number of experience points earned, the quality of crafted items, and your effectiveness with high-tech weapons and terminals.
- 2 Agility (A): It affects your overall movement speed, ability to sneak effectively, and performance in VATS.
- 3 Luck (L): affects critical hit chance, the likelihood of finding valuable items, and the outcome of random events.
Additionally, consider collecting Bobbleheads throughout your Fallout 4 (FO4) adventure. Bobbleheads are collectible items scattered throughout the game world. Each bobblehead represents a particular attribute or skill, and when collected, it permanently increases your character’s corresponding stat or ability.
Best Perks
The best perks for a Demolition Expert build are Demolition Expert, Heavy Gunner, Commando, and Adamantium Skeleton. Three different weapon damage perks can have a stacking effect, meaning one weapon can get boosted by multiple perks if they fire grenades and are fully automatic or have explosive rounds. Moreover, you want an Adamantium Skeleton and Medic for increased survivability and reduced limb damage if you fire a grenade, rocket, or explosives too close.
Here is the list of the best and recommended Perks for the Demolition Expert Build in Fallout 4:
- Demolition Expert – increases explosion size, grants arc, and grenades shot in VATS do double the damage. This cornerstone perk also stacks on other weapon damage perks like Heavy Gunner and Commando.
- Heavy Gunner – increase for heavy weapons, which come later in the game vs. early on.
- Commando is another bonus weapon damage perk for fully automatic weapons and hip fire (not in VATS). All three weapon types can give stacking additional benefits and even more damage.
- Adamantium Skeleton – with explosives, you will take self-inflected damage, and this helps prevents you from being crippled in combat.
- Medic – you will need a lot of burst healing without running Lone Wanderer, and this is very helpful early and late game.
In Fallout 4, perks are special abilities and bonuses that enhance your character’s skills, combat prowess, and survival capabilities. Perks are acquired by spending perk points each time your character levels up. Perks are divided into categories, each corresponding to one of the S.P.E.C.I.A.L. attributes. These perks offer a wide range of customization options, allowing players to tailor their characters to suit their preferred playstyles. However, there are no respecs or redoing of Perks. Thus, your selections are vital to increasing your character’s overall power.
Level Progression
The Demolition Build focuses on explosive, heavy, and automatic weapon damage perks. You can use a variety of weapons, some with stacking damage bonuses. Moreover, you will need multiple defensive and survivability perks, especially at the start, where you won’t have powerful weapons. As the levels advance, you gain more damage and utility perks like crafting, locksmith, and Scrounger. These will help you with general gameplay and keep the ammunition flowing when you need bullets desperately. Lastly, we forgo intelligence to emphasize multiple weapon types and survivability. Beyond level 50, you can increase your intelligence and gain science if you enjoy advanced crafting mods. Or, you can increase charisma and gain Local Leader for settlement gameplay.

Gear, Weapons, Armor
The best items for a Demolitionist Expert build are the Cryolator, Incinerator, and Spray n’ Pray. The Cyrolator is a heavy weapon obtained during the prologue and is powerful throughout the game. Incinerator is the best area-based explosive weapon, and Spray n’ Pray unique effect allows it to use three perks. Moreover, look to obtain combat armor, modify it with padding, and strengthen it to help with survivability.
Cryolator – During the prologue, you can use Dog Meat to grab this item from a locked area and use it as an instantly powerful heavy weapon. Ammunition will be challenging, but follow our quest guide for a considerable advantage starting the game.
Incinerator – when it comes to massive explosive, area-based damage, it is your best weapon. Unlike the Big Boy, this weapon is easier to avoid friendly fire and has multi-kill potential. You can obtain an Incinerator by completing the Crucible quest.
Spray n’ Pray – while Spray n’ Pray seems weak, it has explosive rounds doing AOE damage, thus using Commando, Bloody Mess, and Demolition Expert perks. You can upgrade the weapon with Gun Nut to increase its effectiveness, making it one of the best weapons because of its passive explosive rounds. You can obtain this weapon from Vault 81, in the southwest corner of the map near Oberland Station.
Combat Armor – using your armor perk, make sure to mod your armor with Strengthened in legs and arms for reduced limb damage. Moreover, padding or dense should be used in the chest to reduce damage from explosives.
Companions
Curie is the best companion for the Demolition Expert build. This robot will largely stay out of your way in combat, thus avoiding friend fire or explosives nearby. Moreover, it will unlock a vital companion perk called Combat Medic once max affinity is reached. Gain +100 Hit Points if current Hit Points are below 10% of the maximum. This perk from Curie will help increase your survivability in critical moments near death with little downside. An alternative is to use Dog Meat and take 3 points into the Charisma perk Lone Wanderer.
The companion Curie can be unlocked in Vault 81 after completing the Hole in the Wall quest. Vault 81 is in the southwest corner of the map, south of Oberland Station. Complete the initial quest, max its affinity, and unlock the passive perk to help with survivability.
