Eight skills

Smithing training

Player guide

Starting out
Smelt useful ingots or other supported outputs.
Read the timing card for collection versus attended mode.
Ordinary crafting and anvil repairs do not award Smithing XP.

Building your skill
Combine training with the materials you need for building or upgrades.
Compare recorded output items with relic-action batches.
Smithing-table results also earn progress.

Long-term goals
Plan materials before starting a large smelting run.
Automation does not remove the player-credit requirements.
Check the current timing mode rather than assuming stored output gives XP.

In Minecraft: open /skills, choose Smithing and read How to Train. Its live cards show accepted rates and requirements.
