I'm not sure but this is what I had when I successfully completed desert treasure at 48 combat.
70 Magic
70 Range
1 Defence
11 Prayer
The Bosses
Kamil
Easy (for me anyway) 70 Magic recommended, use fire blast.
59 magic is no good, because the weather conditions lowers your magic.
Get a friend who has completed Desert Treasure. Set up cannon where the trolls are. Load cannon, shoot it. The trolls will retreat, walk in there and lure them towards you, or use your friend as bait. Once you've killed 5, restock and head back.
Walk through the trolls and eat so they don't kill you. Then follow your friend (who should carry extra sharks for you) past the wolves the majority should attack him/her.
Once you get to Kamil, make sure your friend is north of the rock. Walk north, next to him/her. Kamil shouldn't be able to melee you, but he can still freeze you preventing you from attacking him. It is possible to block him, I done it myself. Walk back to the rock whenever you can. Walk out and as soon as you hit the square you're walking to, right click kamil and attack. So you attack just as you turn to face him, then retreat behind the rock and repeat.
Damis
Easy stuff, my friend blocked him for me. Don't know how to explain this much, I used earth wave.
This should work as it did for me.
Dessous
Not too hard, Get a Cannon 30 Cannon balls, an Xbow and 50 bolt racks.
Set your cannon up, just outside the gateway, load it up and fire.
Get Dessous out and run immediatly North-East of the area. He should teleport to you.
Pot up, attack him and the cannon will attack him too.
Just keep eating whenever he hits you.
Fareed
Easy-peasy-lemon squeezy
Magic for water wave/blast, and bring a few snares.
Go inside the cage, snare him, it will splash but it will work. He should just stand there for 10 seconds allowing you to cast your spell.
Keep your distance and when he starts moving again, snare him again.
Repeat and kill him
Pyramid
Keep weight low, Bring 5-10 sharks a tele-tablet, some super energy potions, and a super anti-poison potion.
Get a decent map off any website of the pyramid and just run through it.
If you fall out, restock or just try your luck again.
