How to use this tool?
Follow these steps to calculate the quality of a Giants Foundry sword:
- Select Alloy Type – Choose the primary metal (e.g., Bronze, Rune). This determines base stats.
- Select Secondary Alloy (Optional) – Choose a second metal to mix. If used, you must add secondary bars.
- Enter Primary Bars – Number of bars for the primary alloy (0–28).
- Enter Secondary Bars – Number of bars for the secondary alloy (0–28). Required if a secondary alloy is selected.
- Enter Smithing Level – Your current level (1–99). Higher levels boost quality.
- Click "Calculate Quality" – The form validates inputs and shows results.
Outputs explained:
- Quality Score (%) – Sword quality, capped at 100%. Higher = better XP and tokens.
- Base XP – XP earned before quality bonus.
- Total XP – Base XP multiplied by a quality bonus (up to 1.5x at 100% quality).
- Reward Tokens – Tokens earned (quality score divided by 10, rounded down).
Tip: Use up to 20 bars for full efficiency. Mixing alloys and higher smithing levels improve quality.

Frequently Asked Questions
Quality score depends on the alloy type, secondary metal, number of bars, and your Smithing level. The formula is: Quality = (AlloyFactor + SmithingBonus) * BarCountFactor, capped at 100%. Higher quality yields more XP and reward tokens.
Using Rune as primary and adding a secondary metal like Adamant can boost quality. Generally, higher-tier metals yield better quality, but mixing can optimize the alloy factor.
Using 20 bars total maximizes the BarCountFactor. Using fewer reduces efficiency, but you can still get decent quality with fewer bars.
