You have made the right decision, adventurer. We must strike where we will do the most damage: the four sentry towers. With the four towers in flames, we can initiate an offensive before they have time to react. You will need the proper tool to set the towers ablaze. To make the tool requires some materials. Bring me four hearts of flame and four golem oil and I shall craft the torch of flawless flame. The golems and elementals in these lands should be your first target.
