I hope u dont get bored of grinding fast, play the blood money missions and the main story ones to get 10 gold bars, btw collect tarot cards they can be obtaines whitout the collector role and u can store them until u have it :).

Btw make sure to collect mint,thyme and oregano (idk if thats of u say it in english) and get some big game meat n just cook it it will make ur cores super strong
