Bloody skulls

Bloody skulls are an elemental node in the Runespan that allows players to draw death runes and blood runes from it. They are found on the top floor. It requires level 83 Runecrafting and gives experience in cycles of 144 experience if a death rune is siphoned or 175.5 experience if a blood rune is siphoned, though occasionally will also give 2 experience when a failed siphon is performed.

Unlike creatures, players do not receive any rune essence when a node is depleted of its energy.
