Lootbound Inventory Grid and Item Rotation Guide

How does the Lootbound inventory work?

Lootbound treats the active inventory as the character’s equipment screen and build board at the same time. Public gameplay footage shows that weapons, helmets, boots, and other non-ability items all occupy grid cells and contribute their displayed stats while they remain in that active inventory. There is no single weapon slot to choose: multiple weapons can contribute at once because attacks come from abilities rather than a held weapon.

Area or item type	What it does	Planning consequence
Active inventory	Holds stat-contributing items	Every occupied cell must justify its space
Reserve storage	Holds extra items without adding their stats	Save alternatives for later swaps instead of forcing them into the build
Abilities	Used to attack and act in combat	They are not packed like ordinary equipment
Companion inventory	Gives each companion its own item space	Party members need separate layouts; companions cannot use consumables
Amulets	Buff touching items, with eligible targets depending on the amulet	Placement and contact edges can matter as much as raw item stats

Why do item shapes matter?

Items occupy different arrangements of grid squares. Two items can use the same number of cells yet have very different packing costs: a compact block fits many open regions, while an irregular shape can split the remaining space into pockets that no future reward can use.

Rotation changes the geometry but not the underlying item. Before discarding a strong reward, rotate it through every allowed orientation and test it against the continuous empty region—not just the first visible gap. A layout with two empty cells in separate corners is less flexible than a layout with the same two cells touching.

What placement order should you use?

Use a consistent five-step rebuild whenever a reward or companion changes the setup:

1. Choose the active engine. Decide which ability, damage type, defense plan, or amulet interaction the inventory is supporting.
2. Place the most constrained shape. Start with the item that has the fewest useful orientations or must touch particular equipment.
3. Build the amulet cluster. Put eligible high-value items against the correct amulet edges before filling neutral gaps.
4. Add compact stat pieces. Use flexible shapes around the core instead of letting filler determine the layout.
5. Protect one continuous opening. Leave a region that can accept a future reward without dismantling the entire engine.

This order separates “an item has good stats” from “the full arrangement produces more value.” The amulet and adjacency guide goes deeper into testing which touching items actually receive an effect.

How should reserve storage be used?

Reserve storage is not dead space, but items there do not contribute to the current character’s stats. Use it for pieces that may become valuable after a new amulet, ability, companion, or route reward appears.

Good reserve candidates include:

• an irregular high-value item that does not fit the current board;
• one half of a synergy that is not active yet;
• a compact replacement for a future layout;
• an item intended for a companion whose inventory still needs rebuilding.

Do not keep every low-value item “just in case.” Reserve space also becomes constrained later in a run. Compare a stored item’s realistic next use with the opportunity cost of blocking a better future pickup.

How do amulets change the best layout?

Current gameplay analysis shows two broad amulet behaviors: some can strengthen every item they touch, while others only affect specific eligible item types. That makes contact edges a limited resource.

For each amulet, read the exact current tooltip and answer three questions:

• Which item types are eligible?
• Does the effect require direct contact?
• Which touching item gains the most useful value for this build?

Then compare the cluster before and after the move. A visually tidy inventory can still waste an amulet edge on an ineligible item, while a slightly awkward layout may produce more useful stats.

When should an item move to a companion?

Companions have their own inventories and are AI-controlled in combat. Move an item when it improves the companion’s actual role more than it improves the hero’s board, or when the hero needs the freed shape to complete a stronger cluster. Do not treat companions only as extra storage: their own stats and ability behavior determine whether the transfer increases the party’s total output or survivability.

Consumables are the exception called out in current gameplay footage: companions cannot use them. Keep consumable access with the player character rather than filling a companion bag with items the AI cannot activate.

Which inventory mistakes cost the most?

• Filling isolated gaps immediately. A full grid looks efficient but removes the ability to accept a better reward.
• Judging one item outside the layout. Raw stats do not include the space and amulet edges the shape consumes.
• Leaving alternatives active. A situational piece belongs in reserve if another item contributes more right now.
• Rotating without rechecking contact. A shape may fit while silently breaking an amulet interaction.
• Using companions as storage only. Their inventories should support the party member’s combat job whenever possible.

The broader beginner guide shows where this inventory process fits into route, party, dice, and permanent-upgrade decisions.
