Rift Scuttlers are fairly large neutral monsters found on Summoner's Rift. There are two Rift Scuttlers on the map, one for the top half and one for the bottom half of the river.

The 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 two, she continually moves along a fixed path in the river on the part of the map where she spawns. This makes Rift Scuttler the only (1) non-hostile and (2) autonomously moving monster on the map.

Spawn

Unlike other monsters, Rift Scuttlers spawn with one level below the average of all champions' levels (capped at level 1). At initial spawn, Scuttlers will spawn in the top and bottom river. Both must be killed before the respawn timer activates. Once both initial Rift Scuttlers are killed, only one Rift Scuttler can be on the map at any given time for the rest of the game. Respawn locations are randomly determined, but signaled ahead of time with a respawn marker.

Gameplay

When Rift Scuttler receives damage or gets hit by a hard crowd control effect from any source, she will increase her base movement speed by 100 and attempt 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 dash back down the center and resume fleeing.

Rift Scuttler has several unique interactions with crowd control:

When Rift Scuttler is killed, she will head towards the entrance to the pit of Baron Nashor or Dragon (depending on the part of the map) and will burrow into the ground, spawning an untargetable 500-radius Speed Shrine above her location that grants a 525 sight radius to the killer's team and a brief movement speed boost to champions that cross it for 90 seconds. After the 90 seconds, the shrine will vanish and Rift Scuttler will respawn at her location after her respawn timer has elapsed.
