Junk Hero Shop Guide: How to Spend Scrap Efficiently

To maximize your Scrap efficiency in the Junk Hero shop, hold your currency until your heroes hit major progression milestones—such as leveling up to unlock equipment slots or clearing a boss stage—and spend directly on core offensive upgrades for your primary damage dealers. Avoid spending currency on low-tier gear as soon as it appears or spreading upgrades thinly across your entire roster.

Timing Your Shop Visits

Checking the shop constantly during active wave clearing leads to small, low-impact purchases that drain your Scrap. Synchronize your shop visits with clear progression triggers to ensure the inventory matches your current power level:

• After Boss Encounters: Wait until you finish a boss wave or clear a stage before opening the shop so available gear scales to your updated progress.
• At Hero Level Milestones: Save Scrap until your heroes reach levels that unlock new gear slots or ability nodes, allowing you to equip high-tier items immediately.
• During Inventory Refreshes: If the current shop selection offers minor stat gains, hold your Scrap until the shop inventory refreshes rather than buying temporary gear.

Prioritizing Items by Squad Need

Before purchasing items, evaluate whether your team is failing due to low damage output or poor frontline survival. Focus your Scrap on equipment that addresses your immediate bottleneck.

Prioritize flat stat increases to damage and attack speed over utility items. Boosting your overall damage output allows your team to clear waves faster, which increases your long-term Scrap generation rate.

Scrap Allocation Across Your Squad

Equipping every hero on your roster simultaneously spreads your Scrap too thin and slows overall progression. Focus your resources on a core team of three to four high-performance heroes.

Direct high-tier offensive gear to a single primary damage dealer ("carry"). A concentrated investment creates a strong unit capable of pushing through difficult stages even if your secondary heroes rely on basic equipment. Upgrade defensive stats for your frontline units only when incoming wave damage prevents your primary damage dealer from surviving long enough to clear the stage.
