You are training with a great Arcane Blacksmith, known for creating Magical Items that helped the world in times of need. Your master is well known amongst the Blacksmiths all around the world, and people might react when knowing that you're his apprentice, being either jealous or surprised. You are not very good when it comes to forging Magic Items, but you already know about forgery and have been around magic for quite some time. Since you're new to Arcane Forgery, you are still learning how to create the great Magic Items, but with your master's help, you'll probably be a great forger some day. You can talk to the DM about where your master is established and if you are either with him all the time or getting all the materials you and your master needs or anything else you might think of.
- Skill Proficiencies: You are proficient with Arcana and 1 between Perception and Athletics.
- Tool Proficiencies: You are proficient with Smith's tools and 1 between Carpenter's tools and Forgery Kit
- Languages: You can choose 1 language between Elvish, Dwarfish or Draconic.
- Equipment: You get a Smith's tools and 1 between Carpenter's tools or forgery kit; a Small Pouch; 2 items worth of Raw Materials; 15gp.
You have studied the art of the Forgery for some time, and can turn Raw Materials into brand new weapons, but since you're not that familiar with Magic Forgery, you have to roll with disadvantage for Magic Weapons for a few creations or untill your DM says so.
Suggested Characteristics
You are good when it comes to talking to people because of your time working in selling your goods and to improve the probability of creating Magic Items, you should pick a class/race that sees magic as a natural part of the world.
Contacts
You have a contact in the market in case you want to sell/buy items.

forgery means to fake items. not to forge them
Thank you. English is not my main language, so i apologize for any sort of grammatical mistakes.
So two things, First, I think this is a good idea, but the feature is in my opinion very out of left field. Generally background features don't actually change anything mechanically, and are almost exclusively for role playing purposes.
Second, Generally Suggested Characteristics are Personality Traits, Bonds, and Flaws. In many backgrounds it just says "Use the tables for the ____ background as the basis for your traits and motivations, modifying the entries when appropriate to suit your identity."
In this particular instance, I recommend you just say:
"Use the tables for the guild artisan background as the basis for your traits and motivations, modifying the entries when appropriate to suit your identity."
