well grand exchange is good you can buy and sell. buy for low price sell for higher price. of course make sure profit will be somewhere in thousand or millions since hundreds will take a while. herbs- herbs cost insane but people want them. buy a few ranarr seeds. grow them in different patches but make sure you use super compost and have your magic secateurs. then pick and sell or make into prayer pots then sell. clue scrolls- if you hae nothing better to do, then try clue scrolling although this isnt really good because 80% of the time you get garbage. like my last lvl3 i did yesterday and i had it for 7 months because it took me to major pk zone. i got rune plate as best thing in the end. thats free cash but i did use up some food for those 3 zammy mages i had to fight. plus some revnant ork thing came into my first fight and attackd me idk wtf it is or why though. fletching- high fletching? low fletching? with the req assist it doesn't matter. make some yew bows or magics if you can. and high lach them. fishing- even though sharks are now much less in price, monkfish arent. they heal well, cooking xp is nice. catch faster than sharks. require lower lelvel to fish and cook. are worth good money. and bank is right near them. now id still fish sharks if you can. lastly, go pking...o wait nevermind. honestly best way to make money in my opinion is to eith high alch or buy/sell goods in grand exchange. im doing both now.
