Equipment
Equipment in Undertale consists of a Weapon (affects ATK and sparing mechanics) and an Armor (affects DEF and sometimes grants special effects). You can equip one of each.

Currency
Undertale uses Gold (G) as its only currency. Gold is earned by defeating monsters (both spare and kill), selling items, or finding it in the world. It is used to purchase items from shops. There is no carry limit.
- Earning Gold: Spare monsters for lower gold; kill for higher gold. The golden money bag in some areas grants temporary gold boosts.
- Spending Gold: Most shops accept gold. Notable purchases include healing items, the Toy Knife, and the Notebook.
- Note: Gold is reset on new runs but can be accumulated across saves? No, each save file keeps its own gold.
- Burnt Pan + any healing item: +4 extra HP per heal. Pairs excellently with high-heal items like the Legendary Hero.
- Stained Apron + kill-heavy play: Heals 1 HP per kill, allowing sustained combat in Genocide routes.
- Temmie Armor + healing items: The passive regeneration outside battle makes exploration hazard-free.
- Real Knife + The Locket: The ultimate genocide loadout, but trivializes combat.
- Heart Locket + Notebook: INV stacking makes you nearly invincible during boss fights.
- All Weapons/Armor: To obtain every piece of equipment, you must play through Neutral, Pacifist, and Genocide routes (separate saves).
- True Lab & Gaster: The Empty Gun + Mystery Key allow access to the hidden “Gaster room” for a cryptic conversation.
- Temmie Armor: Requires donating a total of 10,000G to the Temmie College fund (100G per donation, 100 times). Save up before attempting.
- Dog Residue: Collect at least 10 for the “Dog Marriage” achievement (if using achievements).
