Weapons & Armor
Weapons raise AT; armor raises DEF. Undertale keeps numbers readable so you can feel upgrades without spreadsheets. You equip one weapon and one armor at a time.
Finding gear
Explore every room, talk to NPCs, and check shops. Some equipment is easy to miss if you rush. Pacifist-leaning players still benefit from DEF while practicing MERCY timings.
Notable progression (spoiler-light)
- Stick / Bandage — starting loadout; the Stick has joke uses via ACT.
- Toy Knife / Faded Ribbon and other Ruins finds — early readable upgrades.
- Tough Glove, Manly Bandanna, Ballet Shoes, Old Tutu — mid-game AT/DEF steps tied to exploration and shops.
- Burnt Pan, Stained Apron, Empty Gun, Cowboy Hat — Hotland-era options with distinct battle flavors.
- Heart Locket / Worn Dagger and late unique pieces — tied to story locations; explore New Home carefully.
Exact AT/DEF values appear on the stats screen. If a fight feels unfair, check whether you skipped a shop or a side room.
