I have a martial character I want to multi-class into warlock but from what I can see in the book, it looks like they would not receive an arcane focus since they don't get their new class' starting equipment.
How does that work? There's not a price given for the Arcane Focus. Even if there was how would I go about getting one in the case of a warlock? Since the focus would be connected to a being I could not just visit like a Cleric might a temple where would I go to get one if anywhere?
How does a character multiclassing into warlock get a focus? Do multiclassing characters get a free Arcane Focus?
The GM that's running this does not house rule, he's pretty strict about sticking to RAW so please keep answers strictly based on RAW.
