A new system has been introduced to merchants. Basically, you gain material
masteries from working with them. The advantages should be obvious.

Two new ranks have also been introduced; 'Craftsman' for those who are the
material type (metal, gem, wood...) leaders in the merchant guild, and
'Artisan' for those who are specific material leaders (iron, gold,
diamond...).

I'm closely monitoring the change and tuning accordingly.

PS. Those of the merchanty persuasion can find a new room with something
interesting up from the main merchant guild.
