Fields of Mistria How to Expand Inventory

Bag upgrade purchase

Visit the General Store when the shopkeeper stocks the upgrade — usually after introductory town quests. Price is 1000 Tesserae in 1.0 community documentation. Save across multiple shipping days; do not impulse buy if you still lack fishing rod and shovel (~500 Tesserae each).

After purchase, your slot count increases permanently for that save. No secondary bag upgrade is documented at launch — treat 1000t as the critical one-time buy.

PC shortcuts every player should use

Shift + click — moves stacks between open chest and inventory instantly. Place chests on farm near shipping box for morning offload routines.

Ctrl + right-click — splits stacks. Use when packing exact quest deliveries (ten wood for bridge quests, refined goods for greenhouse).

G — throws held item. Discard low-value mine junk after confirming not quest-marked — tablet quests from magic unlock sometimes use ore-like items.

Documented fully on keyboard controls; controller uses menu-based splitting only.

When to buy relative to other upgrades

If you must choose rod or bag first, pick rod for renown unless a mine trip is imminent with full ore stacks piling up.

Mine inventory discipline

Before descending:

• Eat meals from hotbar, not bag clutter.
• Leave gifts and festival items in chest.
• Pre-sort ore into labeled chests after return — reduces next-day bag pressure.

Combat drops fill fast — see combat tips for loot priorities (keep museum-first copies).

Farming and shipping loops

Multi-harvest crops from crop planner outputs fill bags mid-field. Upgrade bag before planting huge summer layouts or automate with statues later from woodcrafting.

Shift-click harvest directly into shipping box when standing adjacent — fewer inventory hops.

Throwaway and storage strategy

Cheap trash goes to G throw or sell bin. Medium goods ship overnight. Rare items go to museum or quest bin chest with sign labels (player habit — not game feature).

Bridge repair quests needing 300 wood benefit from dedicated wood chest near farm exit — walk less, carry less.

Steam Deck note

No shift-click — upgrade bag earlier on handheld-only saves because menu transfers take longer.

After upgrade

Funds tight again — resume crop shipping, request board, fishing. Next economic targets: tool upgrades and Town Rank pushes. Comfortable inventory makes tips and tricks marathon days possible without midnight chest trips.

Chest layout recommendation

Place one chest beside shipping box for sellables, one near farmhouse door for quest items, one mine-kit chest with food and bombs only. Labeling is player habit but saves hours across a year. Before greenhouse material turn-ins, temporarily clear quest chest into labeled stacks — refined stone and glass overflow standard 30-slot layouts even after bag upgrade. On controller, batch-transfer by category every mine return instead of sorting tile-by-tile in the field.

Pre-upgrade warning signs

You need the bag upgrade when mine returns end with discarded ore on the ground, when festival shopping fits zero items, or when bridge material turn-ins require three trips. If two of three apply, delay seed purchases one day and ship extras before buying.
