Any reason we can't use them to either buy Wyll out of his Pact or get Raphael to fix Karlach Engine? Weird we can only use to empower Karlach engine as some sort of insert coin kid machine.
Cut content. There's a few speculations as to what they were for (offered to Withers, payment to Raphael) but they were very obviously supposed to be more than a +1d4 fire damage power-up to Karlach.
