Soul esswraiths are creatures found on floor three of the Runespan. They can be siphoned for soul runes, requiring 90 Runecrafting and one rune essence, and giving one soul rune and 107 Runecrafting experience for a successful siphon. An unsuccessful siphon will give no runes, consume no essence, and give 1-2 experience.
Soul esswraiths can also be "chipped" for rune essence. By using 10 blood runes on the esswraith, you will receive 10-20 rune essence. However, the same esswraith cannot be chipped twice in a row; you can't chip the same creature until you have chipped three other Runespan creatures of any type. Esswraith is a portmanteau of essence and wraith.
