Nature esshound

Nature esshounds are a type of esshound found on the middle and upper floors of the Runespan. They can be siphoned for nature runes, requiring one rune essence and giving one nature rune and 43.33 Runecrafting experience for a successful siphon; an unsuccessful siphon will give no runes, consume no essence, and give 0-2 experience. They require level 44 Runecrafting to siphon. You can absorb 5 nature runes before the esshound dies, leaving 50 rune essence. However, if the player stopped siphoning before the esshound was drained, they will not receive any essence. They respawn every 5 seconds.

Chipping
Nature esshounds can also be "chipped" for rune essence. By using 10 chaos runes on the esshound, you will receive 10-20 rune essence. However, the same nature esshound 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.
