Fastest way to do pre-desert treasure?

quest points: 3

I'm off to get 10 slayer legit and then get whatever's needed for waterfall quest and do that, any quick way to get everything ready for DT in like under 5 hours? (excluding stats, gonna bot them up over night)

Basically looking for any tips like "well if you get 20 agility then you can do something 20 minutes faster in such and such a quest"

High agility and light armor (boots of lightness, Spotted/Spottier cape) would help you a lot. Boots of lightness can be got without doing a quest, Spotted cape will take 30 hunter. They will reduce your weight by 6 kg (BoL & Spotted cape.) Also, Energy restore potions & the Explorers ring 3 would help for the running involved.

Yesterday at 5PM I started all the prerequisites for Desert Treasure, I'm talking skills and quests.
When did I finish DT?
This morning at 4AM.
