Rift Scuttler

Rift Scuttler is a large neutral monster found on Summoner's Rift. There are two Rift Scuttlers on the map, with one found in each half of the river spanning the middle of the terrain.

Rift Scuttler is unique amongst all monsters in the game for two reasons: she will not retaliate against an attacker, instead attempting to flee directly away from them, and she moves along a fixed path in the river on the part of the map where she spawns. This makes Rift Scuttler the only non-hostile and autonomously moving monster on the map.

Gameplay
When Rift Scuttler receives damage from any source, she gains +100 movement speed and attempts to run from the source. She will not attempt to flee from any second sources of damage that appear. If she is forced to the very end of the river, she will perform a dash similar in appearance to back down the center and resume fleeing.

Rift Scuttler has several unique interactions with crowd control:
 * Crowd control effects against her last twice as long.
 * When affected by crowd control that prevents her movement, Rift Scuttler permanently loses 50 armor and magic resist. This can only occur one time after each spawn.
 * While Rift Scuttler is under the effect of crowd control that prevents her movement, she receives 25% extra damage from all sources, including true damage.

When Rift Scuttler is killed, she will head towards the entrance to the pit of or  (depending on the part of the map) and will burrow into the ground, spawning an untargetable -radius  above her location that grants a   radius to the killer's team and a brief movement speed boost to champions that cross it for 75 seconds. After the 75 seconds, the shrine will vanish and Rift Scuttler will respawn at her location after her respawn timer has elapsed.
