Undead soul

Undead souls are an elemental node in the Runespan that allows players to draw death runes and soul runes from it. They are found on the top floor. It requires level 95 Runecrafting and gives experience in cycles of 144 experience if a death rune is siphoned and 255.5 experience if a soul 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.
