Deadlock item upgrades, soul payments and inventory slots

By DeadlockStrat · Reviewed 2026-11-01

Pay the item's full price minus the value of components you actually own and consume. A component cannot remain in your inventory after an upgrade or be credited twice. Normal sale refunds are separate from purchase payments.

Full price is not always the amount you pay

In the Build 6839 reference, Extra Charge costs 800 souls and Rapid Recharge has a full value of 3,200. If you own Extra Charge, upgrading consumes it and requires another 2,400 souls. If you do not own the component, the full 3,200 is payable.

Buying the component and then upgrading spends 3,200 in total, not 4,000. The distinction matters when comparing the next useful purchase with your available souls. The linked item pages show their actual direct components and payment examples.

Recalculate from the inventory after each step

If two upgrades share a component, owning one copy does not grant a discount on both. After the first upgrade consumes it, calculate the second purchase from the new inventory. The same principle applies when a larger upgrade replaces an earlier upgraded item.

Low → High orders the newly calculated payable amounts. It does not sort full shop values and then apply discounts afterwards. This mode is a price order, not a promise that the cheapest item is tactically correct at every moment.

Universal slots and separate active limits

The reviewed standard inventory starts with nine universal slots and can unlock three additional Walker slots. Weapon, Vitality and Spirit items share those slots; they are not separate category inventories.

At most four owned items may have their own actives. An upgrade can consume components and free inventory space, but you still need to validate the resulting inventory and active count. A marker for a Walker slot is a requirement, not evidence that your team has unlocked it.

A sale is not an upgrade credit

The reviewed normal sale refund is 50% of full item value. Selling an 800-soul item returns 400 souls; that is different from consuming it as an 800-soul upgrade component. Immediate shop undo follows different rules and is excluded from the continuation planner.

For a replacement, compare available souls plus the displayed refund with the replacement payment. Keep the sale, refund and payment visible separately. A lower shortfall does not by itself justify losing an essential counter or the item that makes your hero path work.
