In Dungeons and Dragons, my character is a Bard Elf. I have the Bard Starting Package, which includes four starting skills (I can only choose 4 due to modifiers) But after "Knowledge", in parentheses it says "any". Context:
Knowledge (any) Rank 4 Ability Int
Does "any" mean I can choose any kind of knowledge from the skill descriptions, or that I already know all of the knowledge sets? I'm new to D&D so the book I am using may be a bit old and I am still learning.
