Buy OSRS Ensouled dragon head
The Ensouled dragon head is a members-only item in Old School RuneScape. It is dropped by chromatic dragons like green, blue, red, and black dragons. Brutal dragons and lava dragons drop it too. The creature's soul is still inside the head, so it can be brought back to life.
Players use this head to train Prayer. Cast the level 90 Magic spell Master Reanimation from the Arceuus spellbook on it. The spell needs 4 Soul runes, 2 Blood runes, and 4 Nature runes. A reanimated dragon appears. Kill it to gain 1,560 Prayer experience.
The reanimated dragon breathes fire. Use dragonfire protection or fight it from a safespot. The dragon hunter lance works on it.
The head can be reanimated near where it dropped, as long as it stays on the ground in a 31x31 area and does not go into the bank, trade screen, Grand Exchange, or price checker. If it does, take it to the Dark Altar in Arceuus to reanimate it there.
Using a knife on Kbd heads gives three ensouled dragon heads. The item is not tradeable, not stackable, and not equipable.
