Scarabs are lower levelled versions of Scarab swarms, which randomly spawn inside the Jaldraocht Pyramid from cracks in the ground. They are identical in appearance and behaviour to scarab swarms, including their extremely fast attack speed and ability to poison, making them dangerous for lower levelled players.
When these scarabs appear from a crack in the ground, the player they are targeting will stop moving momentarily, leaving them vulnerable to attacks from mummies if they do not have Protect from Melee activated.
Unlike scarab swarms, they are constantly aggressive to all players. If they lose interest in the player they have targeted, they will attack other players that approach them, including the player they were originally targeting.
