So I'm not sure if I'm just missing something but the premade elf in lost mine of Phandelver should only have 4 languages (two from race and two from background) but for one reason it has 5. Can someone help me see what I'm missing?
While elves get Common and Elvish, high elves get an additional language of their choice.
Extra Language. You can speak, read, and write one extra language of your choice. (PHB p.24, "High Elf")
With two more languages of choice from their background this gives a high elf acolyte a total of 5: Common, Elvish, and 3 of their choosing. In the case of the elf from the Starter Set, those 3 are Draconic, Dwarvish, and Goblin.
