Elite Clue Scroll loot
Elite Clues can be 1-4 steps all located in the wilderness.
All of the loots seem to be equally common, with skilling resources being pretty much consistent
Skilling Resources
Barrows and PvP Armor sets
Misc Cosmetics
Boxes
Wizard, Archery, Warrior boxes, gold bags, stone keys all seem to have the same drop rate.
Dragon hatchet and cut onyx is also very common.

You can open these to get different loot.
Unfortunately this is the "best" loot from Elite Clue scrolls as of right now.
