Build Guide: Heavy Weapons with Bulletstorm, VATS, Critical Hits, Crippling

Build Guide: Heavy Weapons with Bulletstorm, VATS, Critical Hits, Crippling

Playstyle: Human | Bulletstorm | V.A.T.S. | Crit Build | Crippled Damage | High DPS | Full Life

The changes to the perk cards for heavy weapons are now complete, so we can finally present a long-term viable heavy weapon build.

This build primarily uses full health and heavy weapons. Power armor isn't strictly necessary, but it does improve certain situations. You have some flexibility regarding your personal power armor preferences. The primary weapons I use here are heavy energy weapons with large magazines for the Bulletstorm bonus: the Gauss Minigun is the best choice. Gatling Plasma or Gatling Laser are also viable options. And if you use "Bandolier", you can also use ballistic heavy weapons like the .50 caliber machine gun or the LMG. It's also perfectly possible to play this build bloodied to enhance all SPECIAL stats and gain benefits such as increased Action Points, Luck, or Intelligence by using unyielding armor.

The bonuses this build utilizes are:

  • Bulletstorm with up to a 90% bonus after 10 stacks.
    For every 30 shots fired, you receive a 9% bonus damage. A maximum of 10 stacks is reached after 300 shots.
  • Critical hits in VATS significantly increase our damage. More than 300% bonus on critical hits is easily achievable. Using VATS allows us to hit much more accurately and consume less ammo.
  • Crippling quickly stops enemies, preventing damage taken. Simultaneously, crippled enemies grant us an average of approximately 175% additional damage from perks.
  • Further bonuses like Adrenaline allow for even greater damage increases.

This build is also suitable for Ghouls, but a separate build guide will be released for them after the next update.

Weapons

The primary weapon here is a Gauss Minigun with the legendary mods: Furious, Vital, V.A.T.S. optimized, and Conductors. The goal is to maximize damage on critical hits in VATS using the onslaught effect.

Other weapons with these legendary mods are also possible, but they usually offer less damage.

Gauss Minigun

Armor

The Power Armor is a Vulcan armor with the legendary mods: Overeaters, Powered, Tru-Hiker, and Limit-Breaking.

This increases AP regeneration by 50%, grants 25% more durability on Fusion Cores, and, thanks to Limit-Breaking, significantly increases the number of critical hits (ideally every second hit). The legendary mod "Overeater`s" grants a damage reduction of 30%, when we're fully fed (which can be easlily permantently achieved by using perfect bubblegum).

Without Power Armor, I'm using Unyielding Secret Service armor with the mods Powered (3x), Poisoners (1x), Fireproof (1x), Thru Hiker, Ranger (2x), and Limit-Breaking (3x). As underarmor, I'm using shielded casual underarmor for increased INT, CHA, and LCK, along with a large backpack for increased carrying capacity.

Using the thru hiker mod on 5 pieces of both armor allows us to completely go without the thru hiker perk card and travel pharmacy, since it already reduces the weight of all chems, food and drinks by 90%.

At low health, this setup provides more luck for more critical hits, more Agility provides more AP for extended VATS use, increased Perception, and so on. So you have flexibility regarding your playstyle. Every playstyle has its advantages and disadvantages.

Skillset / Perks

Strength to 10 (+5 legendary STR): 

Easy Target 3* 75% more damage against crippled enemies
Bringing the big guns 3* Your bullet storm limit it doubled. (20 instead of 10)
Scattershot 2* 20% of the damage dealt to a limb is applied to all limbs on your target. Grants fast crippling.
Bullet Storm 3* Gain 9% damage per 30 ammo spent. 10 max stacks.
Thats a 90% Bonus after 300 shots. 180% when 20 stacks are reached.
Lock and Load 2* You keep half of your Bullet Storm stacks when you reload. +1% reload speed per stack.
This helps to reach the stack limit of 20 faster.
Tightly Wound 2* Weapons spin up 60% faster.

 

Perception to 2 (+5 Legendary PER):

Number Cruncher 3* 2% increased damage per AP cost.
Thats +22% on the Gauss Minigun.
Tormentor 2*

You deal 20% more damage per crippled limb your target has. Since all body parts are "limbs" (head, arms, legs, torso) this is a buff of about 120% in average on a crippled enemy.

Tank Killer 2* Your ranged weapons ignore 40% armor.

Note: Concentrated fire is not mandatory for targeting limbs in VATS anymore if we have more than 5 perception. You can still use this perk, but the listed perks seems more useful to me.

Endurance on 9:

Fireproof 3* Take 45% less damage from explosions and flame attacks. Not to confuse with fire resistance which helps us to not being set on fire.
Starched Genes 1* Grants to keep our mutations even when using Rad Away.
Thirst Quencher 1* Increased Max AP based on END while not diseased. This are +69 Max AP in this case.
Bullet Shield 4* Gain 20% Deflect chance for 6 sec when firing a heavy gun.

 

Charisma to 4:

Strange In Numbers 1* Increases the positive effects of the mutations by +25%, if our team members are also mutated. You should always play on a public team.
Tenderizer 2* Each attack makes your target take increased damage. Each hit increases the damage to an enemy by 0.1%, reaching a maximum of 100% after 1000 hits. This stacks with all other players who have this card equipped and are fighting the same enemy. It also stacks with the legendary perk "Taking one for the team." It's very effective in boss fights.
Inspirational 1* Gain more XP while on a team based on your CHA. In this case we gain about +23% XP.

 

Intelligence to 6 (+5 Legendary INT):

Demolition Expert 3* Your explosions do +60% damage. 
This increase the native Gauss damage on the Gauss Minigun. Alternatively you can use gun smith to increase the durability.
Science! 2* Increase energy damage based on our INT. No matter which weapon you use. If you just want to use ballistic weapons, you don't need this perk.
Batteries Included 2* Reduces energy ammo weight by 90%
Stabilized 2* Big guns gain 30% accuracy. Double in Power Armor.
Good with Salt 2* Food in your inventory will spoil 90% slower.

 

Agility at 5 (+5 Legendary AGI):

Gunslinger Expert 2* +1% ranged weak spot damage per onslaught stack. +3 max stacks.
Guerilla Expert 2* Gain +1% reload speed per Onslaught stack with ranged weapons, +3 max stacks.
Guerilla Master 3* Gain +5% damage to close enemies per Onslaught stack with ranged weapons, +5 max stacks.
Gun-Fu 1* VATS swaps targets on kill with +30% damage to your next target. This is great on mobs and rank 1 should be enough here.
Adrenaline 2* Gain +10% Damage per kill while on a kill streak (max 10). This grants a bonus of +100% after 10 kills.

Note: Gunslinger and Guerilla Perks build up the onslaught mechanic that grants 100% bonus damage together with the legendary mod "furious". Adrenaline boosts the damage in events or crowds on top. And Gun Fu automatically switched from one enemy to the next in VATS.

Luck to 15 (+5 legendary LCK):

The additional 5 luck grant more critical hits. Theoretically you need 16 luck plus "critical savy 3" and 5x "limit breaking" to crit on every other shot.

Class Freak 3* Reduces the negative effects of mutations by 75%.
Critical Savvy 3* Critical Hits now only consume 55% of your critical meter. Critical hits are only applied when the meter is full. The faster the meter is charged, the more critical hits can be dealed in shorter time.
Better Criticals 3* VATS criticals now do +100% damage.
Ricochet 1* Gain a chance to Deflect ranged attacks based on LCK.
Four Leaf Clover 1* Misses in VATS now contribute to the Critical Meter based on your LCK. 
One Gun Army 3* Heavy guns gain a 12% stagger chance and +75% limb damage
Quick Hands 1* Gain a 6% chance to instantly reload when your clip is empty.

Notes: High Luck is essential to land critical hits more often. These Perks help us to get more and stronger critical hits. Ricochet reduces the incoming damage and one gun army grants faster crippling.

Legendary Perks

  • Electric Absorption **** (20% Chance energy damage will recharge your power armor`s fusion core and restore your health.)
  • Taking one for the Team **** (Enemies take 40% more damage when they attack you and you are in a team.) (Experience has shown that this legendary perk also stacks when you are hidden but the other team members are attacked, for example in events. )
  • Legendary Perception**** (+5 PER and +5 PER skill points. Skill points are capped at 15)
  • Legendary Intelligence**** (+5 INT and +5 INT skill points. Skill points are capped at 15)
  • Legendary Agility**** (+5 AGI and +5 AGI skill points. Skill points are capped at 15)
  • Legendary Luck**** (+5 LCK and +5 LCK skill points. Skill points are capped at 15)

By using legendary SPECIALs we can use more points in the skillset than was previously possible. The legendary SPECIALs supplement the points defined for the skillset in the loadout up to a maximum of 15 in the skillset. In addition, the points are applied but cannot be used for perks. For example, if you choose 12 PER in the skillset and have legendary PER at 4*, you still only get 15 points for perk cards, but you have 17 PER in the Pipboy with the active SPECIALs.

Mutations

Mutations are crucial for your gameplay, critical hit damage, intelligence, AP acceleration, and much more. The right combination is therefore important.

  • Adrenalreaction (+6.25% damage per Kill; Max 10 Stacks)
    On the bottom right there is a new skull icon with a counter that shows the Bonus.
  • Eagle Eyes (-1 STR, +5 PER, +63% Critical Damage )
  • Marsupial (-1 INT, +25 carry capacity, +400% jump height)
  • Egghead (-1 END, -1 STR, +8 INT)
  • Herd Mentality (-2 SPECIAL alone, +3 SPECIAL when in a team)
    (so always play in a team)
  • Herbivore (Eat vegetables with no disease with 3X benefit )
    (Negates the effects of meat food)
  • Speed Demon (+25% movement speed, +40% faster reload)
  • Bird Bones (-65% falling speed, -1 STR, +5 AGI)

Buffs

Fully fed: +1 STR, +35 HP, +35 Disease Resist

Fully hydrated: +35% AP Regen, +1 END, +35 Disease Resist

You should always use these two buffs. Both are easy to maintain if you use Perfect Bubblegum (lasts 1 hour). Perfect Bubblegum is available in Foundation and Crater for gold.

In order to get maximum damage on critical hits, this build can use buffs in appropriate situations. It makes sense to buff the damage on critical hits, as well as the ap acceleration / and max AP to be able to act better in VATS.

AP Acceleration:
Either company tea or the combination of corn soup and hard lemonade . Company Tea usually does not stack with other AP regenerating food.
Currently it stacks with hard lemonade, which seems to be a bug.
For situations in which you need more AP for a maximum of 25 seconds, you can also eat several canned coffee and thus get more AP in this time (no acceleration).

More damage on critical hits:
Blight Soup (lasts 30 minutes) or Sweet Mutaberry Tea (lasts 60 minutes) +125% critical damage in combination with Strange in Numbers (+ mutated team members).
Furthermore you can buff the critical hits with the magazine tesla science 9 with +100% more heavy gun damage for critical hits to a total of +225% (blight soup +125% & tesla science 9 +100% = 225% ).
There are also chems to improve the damage: Overdrive also increases the damage from critical hits by +30% 

Max Damage on Critical Hits Combo:

  1. Energy bobblehead (+20% energy weapon damage)
  2. Magazine: Tesla Science 9 (+100% heavy gun damage on critical hits)
  3. Company tea (more AP Acceleration)
  4. Blight Soup or Sweet Mutaberry Tea (+125% damage on critical hits)
  5. Overdrive (+30% damage on critical hits)

Overall: Damage Bonus +20%, Critical Damage Bonus +255% (125+100+30)

Conclusion

This build is perfect for heavy weapon enthusiasts and offers incredible flexibility. Whether you prefer playing in power armor or not, whether you prefer full health or bloodied, this build can handle it all. You can easily switch to power armor when needed and, for example, bloodied in unyielding armor the rest of the time.

Thanks to its high efficiency in VATS and the damage bonuses, ammo consumption is manageable, and collecting contextual ammo helps keep things running smoothly.

Whether you're playing solo, in events, or in a raid team, this build will serve you well. If you prefer solo play, you should still join a public team to take advantage of your mutation bonuses.
