For kbd, avainsies you'd do fine tanking them with b2p tabs but I might find a minute of 65 range first (70-75+ perfered) Barrows that OSRS gold you would be in a position to do today should you maged (Ice charms from ancients are extremely good) For Kalphite queen you need to use a godsword/full veracs if melee-d and in a duo atleast. GWD, unless you maxed your stats (particularly 88summoning for unicorn) you would require a little team to defeat the bosses more than one or two times a excursion. If you havn't been to gwd before then I would recommend you go at a mass first untill you get the hang of it. Heres the link into Sals GWD cs mass that they do two excursions every Saturday/Sunday (depending on your timezone). All the Best.

Dragons are my main source of income for the past couple of weeks since I have started playing again. I'm sick of them, so I'm going to have a visit GWD. Most of my money is going to my abilities, so I'm not spending a lot of cash. My range is 71. Defence will probably be 70 (currently 69) from the time I go. Is that a good set up for what I want to do? Otherwise, what if I substitute? Thanks in advance.

Also, what gear should I bring? ( I will either array or melee him) What strategies should I use to kill him? Eventually, are Level 3 scrolls worth it? Personally if I were you I would wear red d'hide armour, decent melee and good mage defence. You are going to want anti toxin, even drinking it before you commence battle with all the Saradomin Wizards is a good idea since they toxin very readily, and if you forget to flip on shield from melee it is very important you've got it when you initially get poisoned.

Anyways, doing that, and bringing good food, you need to be safe from the wizards. For the dual agent, protect from melee and you won't have an issue. Additionally, the double agent is feeble to cheap RuneScape gold stab attacks, so that's where you certainly want to use your dagger. Finally, I would say Level 3 hints are worth it. They're not exactly rags to riches, unless you're exceptionally lucky, however for the time they consider they are normally a nice little reward, and they're far more fun than just grinding skills. Hope I helped!
