OP C4SH Sleight of Hand Build in Borderlands 4

C4SH is a remarkably adaptable Vault Hunter, and many consider him to be the strongest in Borderlands 4, especially with builds focused on his Sleight of Hand skill tree. These builds offer incredible damage output and allow you to use your Action Skill very frequently.

This build lets you rapidly throw playing cards, allowing you to defeat even the toughest bosses in Ultimate Vault Hunter Rank 6 in just seconds. It also makes clearing groups of enemies easy, without needing to focus on staying alive or mastering complex skills. We’ve included all the details on stats, skills, and equipment you’ll need.

This character build is based on the game as it existed after the April 2, 2026 update for Borderlands 4. Keep in mind that future game changes could make some of the skills used here more or less effective. We’ve also made sure to only use equipment that’s working as intended, so this build should remain powerful and relevant for a while.

How Does the C4SH Sleight of Hand Build Work?

  • Activate Windfall by shooting and reloading (doesn’t need to be at an enemy).
  • Activate the Action Skill.
  • Spam the throwing cards to deal the highest damage possible.
  • When Windfall/Action Skill runs out, reactivate it again with your guns and repeat.
  • This build is designed for immensely easy access for anyone, as all you need to do is shoot things to get Windfall, then activate the Action Skill to spam throwing cards, and repeat.

Best Skills for the C4SH Sleight of Hand Build

Sleight of Hand Skill Tree

Skill Description How it Works
Alchemy (1/5) C4SH gains increased Elemental Effect Chance. Whenever C4SH applies an Elemental Effect he gains a Stack of Fortune. Faster Stacks of Fortune from Elemental Effect Chances.
Fast Hands (4/5) C4SH gains increased Reload Speed. Fortune Stacks gain increased Windfall Chance. Accessing Windfall is essential, as are Fortune Stacks. When using the Hotslugger, that Reload Speed is also going to be great.
Go for Broke (3/5) Whenever C4SH would gain a Fortune Stack, he gains a Chance to gain additional Stacks. The more Fortune Stacks, the stronger the build. Essentially, reloading grants even more Stacks.
Sounds of Rain (5/5) Fortune Skill. C4SH gains a Chance to Critically Hit with Guns, Action Skills, and Ordnance. The more Fortune Stacks he has, the greater the Chance. Increases Critical Hit Chance, which adds even more Damage.
Cowboy (Augment) Whenever C4SH triggers Windfall while his Action Skill is cooling down, automatically Recharge it. Adds an Acid Spray Card that spreads out in a fan in front of him and explodes shortly after impact. Windfall: While Windfall is active, throw additional Acid Spray Cards, and each Card creates a Corrosive Nova on impact. Get your Action Kill faster simply by reloading to get Windfall, and during Windfall, spam powerful Acid Spray Cards.
Devil’s Tines (1/1) C4SH gains an additional Augment Slot. Gain a second Augment Slot rather than being stuck with just one.
Late Scratch (1/1) Whenever C4SH attempts to enter Windfall and fails, he gains a Stack of Fortune. Every time you’re not in Windfall, you’re still gaining Stacks of Fortune.
Payout (5/5) C4SH’s Fortune Skills gain increased bonuses. Massive bonus damage and other stats.
Tender Hearts (5/5) C4SH gains increased Critical Hit Damage. Windfall Skill: While Windfall is active, C4SH gains a Chance to Critically Hit with Action Skills. More Critical Hit Damage and Crit Chance means more bonus damage.
High Roller (5/5) C4SH gains increased Gun Damage. The more Action Skill Cooldown he has, the greater the bonus. Greater survival when you don’t have your Action Skill ready, as you’ll deal more Hot Slugger damage.
Vigorish (5/5) Fortune Skill. Whenever C4SH deals Damage with an Action Skill, his Guns deal Bonus Elemental Damage of that type. The more Fortune Stacks C4SH has, the greater the bonus. Bonus Elemental Damage when you come out of the Action Skill, which helps the Hot Slugger.
The Cooler (Augment) C4SH doubles all Windfall bonuses. Adds a Freezing Shards Card to C4SH’s Deck that automatically Freezes enemies on impact and deals Cryo Melee Damage. Windfall: Whenever the Freezing Shards impact anything, they shatter into Mini Shards that home in on nearby enemies that have a Chance to Freeze them on impact. Cowboy and The Cooler mix well to throw Corrosive Cards, then Cryo Cards to nuke bosses.
Ace in the Hole (5/5) Fortune Skill. C4SH gains increased Gun Damage for every Stack of Fortune. Even more damage for the Hot Slugger.
House Edge (1/1) Whenever C4SH enters Windfall, he only consumes half his Fortune Stacks. Keep your Fortune Stacks, as they halve the amount used in Windfall.
Around the Corner (2/5) Fortune Skill. C4SH gains an increased Action Skill Cooldown Rate for every Stack of Fortune. Helps with Action Skill Cooldown Rate, but it’s mainly for reaching Ante Up and No Limit.
C4SH Game (2/5) All Fortune Skills act as if C4SH has a minimum number of Fortune Stacks. Helps with Fortune Skills, but it’s mainly just for reaching the essential Ante Up and No Limit.
Ante Up (5/5) C4SH gains increased Gun Damage and Skill Damage. The more full his Gun’s Mag is and the more Fortune Stacks he has, the greater the Bonus. Helps stack Gun and Skill Damage with Hot Slugger.
No Limit (5/5) C4SH gains increased Max Fortune Stacks. Fortune Stacks have decreased Chances to enter Windfall. It may decrease Windfall chance, but it’s worth it for the +10 Fortune Stacks.
Card Sharp (3/5) Sleight of Hand does not consume Charges for a few seconds after activating it if Windfall is active. A few extra seconds of free Charges when using Action Skill and Windfall.
Hot Streak (1/1) Whenever C4SH gains a Stack of Fortune, the next time he damages an enemy with a Gun or Action Skill it automatically Critical Hits. This shot deals increased Critical Hit Damage. Saved for the Action Skill, as your card will deal mega damage.

This build is using the Sleight of Hand blue skill tree only.

Best Loadout for the C4SH Sleight of Hand Build

Hotslugger Shotgun

  • This is the only weapon this build needs, as the extra Damage and Stacks annihilate. This weapon is also perfect for Fortune Stacks, as it reloads extremely fast after just one shot.
  • Blazing Barrel: On kill, deal +30%Damage for 10 seconds for a Maximum 3 Stacks.
  • How to Get: Farmed from Callous, Harbinger of Annihilating Death in the Craven’s Nook Bunker in the Heart of the Mountain.

Repkit

  • Any Repkit that you find with Accelerator is useful, as this will grant an increased Action Skill Cooldown Rate by +100%, which means faster cooldown to get back to your Action Skill.

Ordnance

  • You really can’t go wrong with the Jakobs Crit Throwing Knife, as this is always a must in UVH6 for the extra Crit Damage stacks.

Gamer Class Mod

If C4SH lands a critical hit with a gun, the enemy will start bleeding. If C4SH then finishes off a bleeding enemy with another critical hit, he has a 7% chance to create a Chaos Totem. This chance doubles while Windfall is active.

Extra points in Tender Hearts and Skill Critical Hit Chance are helpful, but randomly rolled.

How to Get: Farmed from Nightmare Rift Bosses in Mad Ellie and the Vault of the Damned DLC.

Watts 4 Dinner Shield

  • Overshield Eater – When Energy Shield is active, enemies have a 12% chance to drop an Overshield when hit. When Overshield is also active, it grants +25% Shock Damage.
  • Siphon – When dealing Damage, 10% chance to grant Overshield.
  • How to Get: Farmed from Origo in the Vault of Origo, Terminus Range.

Enhancement

The Enhancement isn’t particularly useful, but any Jakobs weapon will be beneficial because it complements the Hot Slugger build. However, the Hot Slugger is already very powerful with the current skills and equipment.

Firmware

  • Skillcraft (3/3)
    • Skill Damage and Skill Critical Chance are increased, and dealing Skill Damage increases Skill Damage by up to +50%.
  • Heating Up (1/3)
    • Increase Gun Reload Speed for the Hot Slugger.
  • GOOFJC (1/3)
    • Action Skill Cooldown Rate is increased by +10%. Not essential, but a nice bonus.

  • The Best Defense (20 Points in Survivor)
