Smithing

Smelting Bronze Bars

Bronze bars require 1 copper ore + 1 tin ore smelted at a furnace.

How to Smelt

Some furnace spots pair the real furnace with an inert, option-less decoy loc one tile away — a bare name match can pick the decoy and smelt nothing, with no error. Use {withOption} to get the real one. Using ore on the furnace is the portable low-level fallback:

const state = sdk.getState();
if (!state) throw new Error("No world state");
const copper = state.inventory.find((i) => /copper ore/i.test(i.name));
const furnace = sdk.findNearbyLoc(/furnace/i, { withOption: /smelt/i });
if (!copper || !furnace)
  throw new Error("Copper ore and a usable nearby furnace are required");
await sdk.sendUseItemOnLoc(copper.slot, furnace.x, furnace.z, furnace.id);
await sdk.waitForCondition(
  (next) => next.inventory.some((item) => /bronze bar/i.test(item.name)),
  10_000,
);

• Use copper on furnace — it auto-consumes 1 tin from inventory
• Low-level calls do not dismiss level-up dialogs; use bot.dismissBlockingUI() when a modal interrupts a batch
• Each bronze bar gives 155 xp (at level 1-14 range, leveled from 1→14 with 10 bars = 1550 xp total, so ~155 xp per smelt)

Furnace Locations

Location	Coordinates	Furnace IDs	Notes
Lumbridge furnace	(3225, 3256)	2785, 2781	Right next to spawn, reliable. 2781 has Smelt; 2785 is a decoy.
Al Kharid furnace	(3273, 3184)	2785, 2781	Needs 10gp toll gate. 2781 has Smelt; 2785 is a decoy.

Anvil Locations

Location	Coordinates	Anvil ID	Notes
Varrock (west)	(3188, 3421)	2783	Multiple anvils in smithy, near west bank

Also anvils at (3188, 3424) and (3188, 3426) — same building, same id 2783.

How to Smith at Anvil

Prefer the high-level helper, which opens the interface and observes Smithing XP:

const result = await bot.smithAtAnvil("dagger", {
  barPattern: /bronze bar/i,
  timeout: 10_000,
});
if (!result.success) console.warn(result.reason, result.message);

Requires hammer in inventory (buy from Lumbridge General Store for 1gp).

XP Rates

• Smelting bronze bar: ~155 xp per bar (includes level-up bonuses)
• Smithing bronze dagger: ~312 xp per dagger at level 14-26 range
• 10 bars smelted: 1→14 Smithing
• 10 daggers smithed: 14→26 Smithing

Workflow

1. Mine equal copper (rock ids 2090/2091) and tin (rock ids 2094/2095) at SE Varrock mine (3285, 3365)
2. Walk to Lumbridge furnace (3225, 3256) → smelt into bronze bars
3. Walk to Varrock anvil (3188, 3421) → smith into items (requires hammer)

Key Locations for Full Loop

Step	Location	Coordinates
Mine	SE Varrock mine	(3285, 3365)
Smelt	Lumbridge furnace	(3225, 3256)
Smith	Varrock anvil	(3188, 3421)
Buy hammer	Lumbridge General Store	(3210, 3244)

Route: Mine → Furnace → Anvil

This is a long loop. Consider using Varrock West Bank (nearby anvils) to store bars between trips.

Use sdk/API.md for the current smithAtAnvil product and option signature rather than hard-coded interface component IDs.
