Search for its spawns! Gather an army and destroy this threat!</em>"</li><li>You'll be able to see it on your Cyclopedia map whenever you log in as a raid notification.</li></ul><div>You notification.</li></ul><p>You will however still need to check the spots where Abomination Spawns spawned but with the raid notification at least you are aware they exist somewhere.</div>somewhere.</p>
