Giants' Foundry
Giants' Foundry drop table and XP rates: the odds over any number of ore packs, and how many swords it takes to reach a level goal.
Ore type distribution
| Item | Quantity | Rarity |
|---|---|---|
| Coal | 1 (noted) | 1/1.2 |
| Iron ore | 1 (noted) | 1/9.9 |
| Mithril ore | 1 (noted) | 1/15.5 |
| Adamantite ore | 1 (noted) | 1/65.8 |
| Runite ore | 1 (noted) | 1/357.1 |
Experience rates
At 16.0 swords/hour, about 3.8 minutes each:
| Skill | XP per sword | XP per hour |
|---|---|---|
| Smithing | 23,053 | 368,848 |
A 14 adamant + 14 rune sword is 23,053 Smithing experience and 188 reputation, with the shop moulds unlocked — the article’s figures for that blend.
Reputation is the sword’s quality, so the experience and the loot come off the same roll of the dice. An ore pack is 200, which a sword covers 0.94 of.
The rune blends need 85 Smithing and the mithril one 70; the calculator drops to whichever you can actually make.
Jagex’s own comparison puts the pace between 20 swords/hour on the cheapest alloys and 12 on the dearest; 16 is the money-making guide’s figure and the default here.
