|Examine||An esshound imbued with cosmic energy.|
Although the requirement for Cosmic esshounds is 27 Runecrafting, they are only found on the middle and upper floors of the Runespan, thus making the requirement 33.
Cosmic esshounds can also be "chipped" for rune essence. By using 10 earth runes on the esshound, you will receive 10-20 rune essence. However, the same cosmic 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.

Cosmic esshounds can be found on platforms 9, 10, and 14 of the upper floor.
- Esshound is a portmanteau of essence and hound.
