Equipment adjacency
Equipment effects depend on nearby types, direction or distance. Moving one item changes several relationships, turning layout into an effect network.
The player's decision
Boost one strong weapon or place the amplifier between two weaker items?
Original scenario
Original setup: a rune grants +2 to weapons above and below, not sideways. A two-cell sword may displace another weapon, so the strongest item need not yield the best total.
Start with this prototype
Build a three-by-four bag, two weapon types and one directional rune. Show active links and total output. Reach a threshold with keyboard/tap movement and undo. Omit auto-battles and large item pools.
Change one variable
Compare all-direction with vertical-only adjacency for decision depth and explanation cost.
What to observe in a playtest
Are old bonuses removed after moves? Does rotation follow the stated item-relative or bag-relative rule?

Original analysis · version 1
Common pitfall
Mutual amplification needs bounded propagation or snapshot resolution. Derive highlights from the same rules.
Observations and sources
Cases refer to public documentation. Developers and community wikis are credited separately; document review is not a claim of hands-on testing.
- Backpack Hero
The developer explicitly connects placement with increased item power.
- Backpack Battles
Purchases and placement jointly shape builds, with varied item sizes and shapes.
