Unlike gold and food which can be collected from dominion, iron and wood can be collected as below.

1. Gathering

You can gather by sending gathering army to mine and sawmill at the field.

You can collect more resources faster from higher mine and sawmill.

When you collect more than a certain amount of resource or collect all the resource, random item reward including commander equipment material is provided.

Tip) Use Enchant Castle or Guild Blessing to gather resources more efficiently.

2. Occupying land

When you occupy vacant lands near castle, you can obtain iron and wood regularly.

The higher the occupied Land level is, the more resources will be produced.

You can check level and obtainable resource by tapping occupied land in the field.

Please refer to that the number of lands you can occupy is decided depending on your Headquarters level.
