Brackern

Surrounded around the Shuriman Continent are several clans of Brackern, including clans in the Shuriman desert.

Dormun

• Dormun 1
• Dormun 2
• A depiction of a Mwatis

1/3

The Dormun are gigantic, slow-moving creatures protected with large chitinous plates covering their body. In the harsh conditions of Shurima they have evolved to survive the perpetual drought by utilizing an unknown sense to locate hidden reservoirs of water. Incidentally, certain nomadic tribes have built themselves a permanent home upon the backs of these beasts where they clean the creature and hunt any airborne pests who venture near.

Eka'Sul

Desert goats that travel in herds.

Mwatis

Mwatis are goatlike creatures with large plated casques on their heads. Mwati wool and plate are prised for felting and insulation.

Kmiros

Gigantic scarabs that roam in swarms, looking for unfortunate travelers to feed on. They seem to be common prey for Rammus.

Outerbeasts

Main article: Voidborn

• A Xer'Sai known as Rek'Sai
• Kai'Sa fighting Outerbeasts 1
• Kai'Sa fighting Outerbeasts 2
• Kai'Sa fighting Outerbeasts 3
• Kai'Sa fighting Outerbeasts 4

1/5

Beside the Xer'Sai, other creatures from the Void, referred to as 'outerbeasts', can be found in the desert.

• Xer'Sai: Creatures from the Void that plague the southern deserts. They are the size of big dogs on average, but can be smaller or much bigger. Rek'Sai, as the queen, is by far the largest and most dangerous of her species. Xer'sai burst from their small burrows and ravage anything nearby, to the detriment of desert caravans. Once dead, the Xer'sai decompose at an abnormally rapid rate and become inedible.

Ralsiji

• A Ralsiji
• A Shuriman Camel 1
• A Shuriman Camel 2

1/3

Large and aggressive minotaur-like creatures. They are humpbacked quadrupeds with long limbs and thick horns.

Shuriman Camel

A breed of camels native to the deserts of Shurima and are used by caravans as well as common folk as primary mode of transportation. Despite being well-suited for lengthy travels in the desert landscape, they are still prey to a many predator such as the Xer'Sai.

Sandswimmers

Sandswimmers

Sandswimmers are massive quadrupedal creatures that traverse the Shuriman desert in cyclical patterns. They got their name due to their preferred method of travel. Their narrow bodies and webbed feet are perfectly design for swimming under the sand. They feed on bugs and other small creatures most desert beasts ignore. Scavengers will often memorize the predictable paths these creatures take, and jump onto their backs to ride as far as they wish.

Skallashi

• Skallashi
• Skallashi in The Great Sai
• Skallashi at The Zoantha Cascade
• Skallashi near The Sun Disc
• Skallashi in Nashramae

1/5

The Skallashi are large quadrupedal herbivores. These hardy beasts of burden are common across Shurima, ideally suited to the harsh desert environment. Their key body feature is their long legs. Notoriously bad-tempered, they are nevertheless treated with great reverence. Their brown hides are often painted with sacred symbols of protection, and their horns hung with totems and charms. While these creatures are mostly used for travel and carrying heavy loads, on some larger skallashi people are able to built miniature rooms for more comfortable travel. To own one is often considered a sign of considerable prosperity.

• This ability will cast from wherever the caster is at the end of the cast time.
• Upon touching Acceleration Gate, the enhanced missile gains its remaining range equal to [ 1600 units - travelled distance of the standard missile ].

    • For this, Jayce must stand inside or very close to the Acceleration Gate, or place it very close to himself right after Shock Blast's cast time.
• Shock Blast's effect radius is centered around the location of the missile as it collides.
  • Shock Blast will always damage the enemy it collided with, even if it is so large that it is outside the effect radius.
