@JeremyECrawford In the Artificer, it says proficient with heavy crossbows, but the starting equipment says you start with a light crossbow. Is it safe to assume proficiency with light crossbow & the heavy was a typo?

A light crossbow is a simple weapon (see PH, p. 149).
If a character is proficient with simple weapons, the character is proficient with light crossbows.
The artificer is proficient with simple weapons. The artificer is therefore proficient with light crossbows. #DnD https://t.co/VJ92q01KG3
