Mastering Joule Box Upgrades in Mina the Hollower: Your Ultimate Guide to Dominating the Sidearm
Joule Box upgrades are essential for players looking to enhance their sidearm charges in Mina the Hollower. Starting with a base capacity of 20 joules, each joule box upgrade adds 10 charges, allowing players to reach a total of 100 joules when fully upgraded. Locating these joule box upgrades requires skill, patience, and strategic exploration. Below, we detail every joule box location and provide tips to overcome the challenges that guard them.

Zone 1: The Mines of Molten Stone
Location 1: Lava-Filled Chamber (Coordinates: X-47, Y-12)
This joule box is hidden behind a crumbling wall in the eastern wing. Players must perform precise platforming across unstable rock formations and deal with fire-spewing enemies. Clear obstacles with your sidearm before claiming the joule box upgrade.
Location 2: Forgotten Ore Depository (Coordinates: X-33, Y-28)
Located under a pile of explosive crates, this joule box upgrade requires careful detonation. Players must solve a nearby pressure-plate puzzle to disable traps and then blast the crates to uncover the prize.
Zone 2: The Abyssal Trench
Location 1: Submerged Cavern (Coordinates: X-82, Y-55)
This underwater joule box is locked inside a coral-encrusted chest. Equip diving gear and fend off aggressive aquatic enemies to unlock the joule box. Remember to surface periodically to avoid oxygen depletion.
Location 2: The Trench’s Edge (Coordinates: X-91, Y-73)
Situated on a narrow ledge, this upgrade requires grappling hook skills. Players must defeat a patrolling boss enemy and navigate collapsing platforms to secure another valuable joule box.
Zone 3: The Skyward Spire
Location 1: Wind-Swept Balcony (Coordinates: X-15, Y-44)
Accessible only via a high-speed zip line, this joule box is guarded by wind gusts and aerial drones. Time your approach to avoid attacks and land safely on the platform to claim the joule box.
Location 2: The Spire’s Peak (Coordinates: X-05, Y-90)
The final upgrade is positioned at the highest point on the map. Players must navigate through a gauntlet of laser turrets and solve a rotating pillar puzzle to claim the ultimate boost to their sidearm charges and secure the last joule box.

Players should prioritize upgrades in zones that align with their playstyle: tackle the Mines of Molten Stone for combat-focused gameplay or the Skyward Spire for those who excel at platforming. This comprehensive guide will help players dominate the battlefield and master their sidearm abilities effectively.
