title basically, for some context i got a bit under 1b to spend (bank, sacks, i got a scatha upgrading in kat i might sell) and i've been grinding mining recently and just hit mining 60.

thinking of either gdrag, term, hype, or general gear upgrades (mp, gemstones, that type of stuff) but i feel like i might have more important things to upgrade

and for what to grind, basically any of my unmaxed skills or dungeons/slayer
