Don't forget to learn how to properly lure

Brody's manual that Dei You  OSRS gold linked. 'nuff said. You might want to explore the options provided by Barrow, for instance, you could bring a Verac's skirt for prayer bonuses and range defence, or other Barrow's legs that are used to defend against range. You might also want to take a shield in order to compensate for a lower defence level. Make sure to apply for an SGS loan if you are unable to afford an Enhanced Excalibur at minimum.

You'll also need more brews to make up for the lack of experience until you've become accustomed to the idea of it. I recommend bringing one or two Prayer Renewals (if you are aware of the best time to use these) to supplement the prayer restores/super restores that you'll use. If you're using a mixture of super restores and prayer you should only use super restores after you've brewed.

Don't forget to learn how to properly lure and what you should do when you encounter Jad... Since it's a pain to be KO'd before you even see him on your screen. Learn a few videos on prayer switching (that include in-game audio) This will be the most with Jad If you've never done it before. Utilize the 1m of bolts/arrows until you reach the 70 before you even take a second to think about it.

What is your overall stats? It's not advisable to do this much in combat under 90, as it will wreck you, and you'll never make any money (even when you're at level 95. Last time I tried this, it came out as a loss for me due to the fact that the food items plus the prayer pots cost more than the loot)

I'm a noob. My total level  buy rs 3 gold is only 437. I'm not able to figure out my overall combat level however my attack is 32, Strength 15, Defence 23 ranged 6. Prayer 20 Magic 49. I'm totally out of balance. When I first started playing, I wanted to become a formidable mage, so that's where I put the majority of my effort. The only reason my attack is as fast as it is that I enjoy beating up bears and unicorns using my bare hands and no armor.
