Douglas is a talented smithy in Eiyuden Chronicle: Hundred Heroes ready to offer his support both in and out of battle. Once you have him on your team, leveling up your weapons will be easier than ever.
You can find Douglas in the Smithy at Eltisweiss while doing the New Forces segment of the story. He will ask you to bring him 10 iron ore before he will join you. As you're collecting ore it is important not to return to your HQ as these resources will automatically get stored for your town and cannot be pulled. Iron ore can be found in the Abandoned Mine (leave out the Grum County exit instead of the castle well ladder) and a few in Shandar Ridge - South. Once you have 10 and talk to him again, he will join you.
Role: Support
Support Skill: Soul of Smithery - Hone all allies' weapons, increasing their attack strength.
To the east of your castle, Douglas opens a Smithy station where you can improve the weapons of your traveling party and anyone you've recruited.
