Wilderness green dragons with the Wilderness elite diary
Abyssal whip: ~111k xp/h, 255 dragons/h
Dragon scimitar: ~98k xp/h, 220 dragons/h
Required:
POH and respawn point in Prifddinas, locator orb (or dwarven rock cake), antifire potions, fairly clean looting bag.
Summary:
Kill green dragons north of the Graveyard of Shadows. Pick up the bones and reanimate the heads as you get them. Ignore the hides. Camp Piety, and use the dragon dagger special attacks + Death Charge. A trip will take 48 minutes with the setup below.
When deathpiling, use the deposit-x option on the looting bag to get small stacks of runes and noted 4-dose potions in the inventory. Drop the small stacks of potions and runes before deathpiling and pick them up after. Unnote the potions at the Ferox Enclave, exit north, and run north to the dragons.
Offer the noted bones at the chaos altar in the Wilderness. If you already have a big stack of bones, bring 200–250 noted bones per trip.
Alternatively, you can do a shorter green dragon trip (~150–175 bones) and offer them right after the trip.
