Ehhh everyone is wrong. Making winter storage scrolls out of pak yak pouches is the best money for a "skill". Last I heard it was 2m+ an hour. Requires 96 summoning though which I doubt you have.
combats good. Made 50m+ getting 90-99 attack +90-95 str at tzhaar. Minings okay, not that much cash only made 40m getting 99. RC is the best I think 99 makes you well over 200m last time i checked.
