Sorry for the late reply but I made a new channel “Sam69” and there is a way to speed it up first if you play on console like me go to settings then enable console commands then save and press options go into the command input and type slomo 1000 and once finished type slomo 1
Kill the bosses on island/ scorched earth and higher difficulty you do them on the more elemental you get, also recommend using an army of rexes and a yuty for the boss fights
The mod currently does not let you mix anything together by my knowledge since I last played it and sorry I never replied but I switched channels so now I’m using this one
