[RPG] Is it balanced to replace a musical instrument proficiency from the character’s background with an artisan’s tool proficiency instead

backgroundbalancecharacter-creationdnd-5eproficiency

I'm designing a Wood Elf Outlander Warlock (in D&D 5E) who only has one hand. This makes my arm near to useless. As an Outlander, I am proficient with a musical instrument, and have skill proficiency in Survival.

I have designed the character as a self-sufficient hunter, who uses everything from a kill: hides for clothes, meat for food, and bones as a carving medium.

What I would like to do is trade the musical instrument proficiency for a proficiency with a type of artisan's tools that would be used in carving bones into practical things I could use, or decorative items I could sell.

Would this trade-off be balanced?

Since a musical instrument is a potential spellcasting focus, I wasn't sure.


I've asked a follow-up question here: What kind of tools would be used to carve bone?

Best Answer

Yes, it would be acceptable.

Tool proficiencies are not used often (unless it is in Thieves Tools) and their influence on the game is minimal. So, switching musical instrument proficiency for artisan's tools proficiency should not imbalance the game. Rules for background customization (PHB 125) states: "choose a total of two tool proficiencies or languages from the sample backgrounds", further proving that switching one tool for another for your background is supported by the game.
