I suggest you concentrate on Slayer for the time being

If you do OSRS gold Fairy Tale part 3 and also The Elder Kiln, you can reach most places in RuneScape within minutes. I would say complete Shilo Village and visit Duradel. When you hit 75 slayer, visit Kuradal in the Ancient Cavern, and then proceed to Morvran to your closing few levels. As for herbs, I believe RuneScape Wiki includes a spreadsheet with all the very best herb to now do. Usually, snapdragons, toadflax and ranarr are safe options.

I suggest you concentrate on Slayer for the time being; it's profitable (more so at higher levels, but still profitable) and also you train the majority of your abilities while slaying. Also, I suggest obtaining 80 dungeoneering to get a Chaotic. Until then, try to get 70 attack to get a Whip. Lastly, I suggest that you do some quests now. A good deal of your skills are reduced, and the xp rewards will help you skip some instruction. And glad to hear you've got membership!

Barrows is grade 70 tank armor, so it's somewhat on accord with GWD armor. Barrows supplies more defensive boosts whereas GWD provides offensive boosts. I would avoid using barrows for normal slayer as it is not going to be well worth the repairs. Dragon rider is really costly, and you merely have 4m to spend. I suppose you could stick with the grade 50 mage/melee armors for today (Rune, Batwing) since the tier 60 ones (dragon, infinity) are a small leap in price. You should be fine with range as dragonhide is cheap (Royal is tier 65, costs maybe 30k for entire set?)

This necessitates Plague's End, which subsequently requires 11 level 75 abilities along with a buttload of quests. Will take some time.

2h Weapons and dual wield is the thing to do now. You should only utilize safeguards for challenging slayer activities or dragons (in case you do not have any antifire pots). If I were you I'd purchase a dspear, as that is a inexpensive tier 60 melee weapon (you could also go for double wield dlongs/dscims). For mage, do OSRS Money the Mage Arena (in the wilderness) and find a god team. For scope, get an elder shortbow. That is all I can think of.
