For gear, I don't believe you need Void. 1 reason is your Magic level is high enough to RuneScape gold hit continuous 200's/300's on Rex with adverse Magic boosting gear. That's if you use COG and Charge. Or however they're spelled will hit a lot on you. Even with my 91 Defence, and sporting mostly Veracs when I mage they still do damage. So my suggestion for gear would be either Guthans (should you want to heal on Spinyolyps), or even a Veracs mix. These two work fine and have their benefits. Just make certain that you have a Voids Mace/Staff of Guthix so you can use Claws of Guthix. Which works very well.

So I've decided that, hypothetically (since I know I'm likely to give up at any point), I'm opting for a whip. Now to do this I will need 70 assault (not worried about that) but I'll also need a few million coins, which currently I don't have. I imagine my overall bank worth is probably around 500-1000k, therefore not too much, and I'm not actually wanting to sell any of this unless I must. The majority of that is caught up in a pair of dagon'hai robes, a pair of rune armour, and a monster scimitar.

Now I know some ways to buy OSRS gold get cash, but one I've never tried is using combat. I am thinking of attempting to kill green dragons, unless you have any other particular suggestions? Currently my hypothetical set up for green dragons is consequently: Neit Helm. Rune Platebody. Rune platelegs.
