Items are passive bonuses
Items in Brotato sit on your stat line as passive bonuses. A flat item adds to a stat. An effect item changes weapon behavior, like pierce or chain lightning.
The best items echo your build. An item that adds your damage group helps. An item that adds a tag you ignore wastes the slot.
Upgrading weapons
Weapons can be upgraded with materials to raise their tier and stats. Upgrade the weapon that anchors the build, not a filler you plan to replace.
A higher tier adds damage and often range or attack speed. Upgrading early is tempting, but buying the right weapon first is usually cheaper.
Stacking rules
Most items stack by their own line. Two items that add Armor both count. An item that grants a behavior, like lifesteal, applies on top of your base line.
Avoid stacking a stat you already saturate. One strong line beats three weak ones that pull the build apart.
When two items repeat a stat you already cap, skip both and buy the missing defense instead. Upgrade the anchor weapon before buying a third or fourth weapon — tier beats variety when materials run short.
Where to go next
Read the weapon database for every weapon’s tiers. Then see the shop guide for when to buy versus upgrade.
