The Trashmobs of the Underbog

Underbats - Elite version of the common Sporebats found in Zangarmarsh. Have an AoE knockdown ability. Typically come in groups of 3-4 or with Underbog Shamblers. Can be polymorphed and trapped.

Underbog Shambler/Frenzy - Nature elementals which can afflict their target with a disease which inflicts nature damage the next 5 times that target takes damage. Also a Frenzy variety which enrage and deal increased damage. Can be banished and trapped. Shamblers heal themselves and others.

Bog Giants - Powerful giants with extremely damaging melee attacks. Can be picked with herbalism once killed. Immune to all forms of crowd control.

Fen Rays - Elite version of Marshfangs found in Zangarmarsh. Casts Psychic Horror, horrifies the target for 2 secs. Psychic Horror is targeted, not AoE, and is used only on the 2nd person on the aggro list. "The Fear Wards - they do nothing!". Of particular interest to hunters, as they are the only nether ray with normal stats. They can be both polymorphed, and hibernated by druids. In heroic mode, however, they can only be stunned. They automatically unstealth players by mere proximity, making stealth useless against any group that includes them.

Lykul Stinger/Wasp - Bee-type mobs which inflict a poison which deals minor nature damage. However, targets which are inflicted with poison from both a Wasp and Stinger take sharply increased damage. Cannot be polymorphed, but can be frost nova'd. Can both be trapped by hunters, and Wasps should be killed first in a mixed mob group due to their relative weakness and poisons. The poison can be interrupted or spellreflected.

Wrathfin Naga - Humanoid mobs which inflict a bleed that deals significant melee damage and cannot be dispelled. Can be sapped, polymorphed, trapped, and seduced. In Heroic, Wraithfin Sentry are immune to seduce but can still be sheeped.

Murkblood Lost Ones - Humanoid mobs Spearmen (flings spears and cast Viper Sting), Tribesmen, Oracles (casts Fireball) and Healers (casts Holy Light, Heal and Prayer of Healing}. Come in groups together. Healers will cast Prayer of Healing if left alone which will completely heal all nearby Murkbloods and Wrathfins and so should be killed first or crowd-controlled until last. The heal is interruptible.

Underbog Lord - Even more powerful Bog Giants, found before the final boss. Will start by hitting for 6-8k on plate in heroic mode, and must be dropped quickly as they grow in size and power over time. Immune to cc/slowdown, very large aggro radius. They have a kickback ability which hits for 6k on plate, so the MT must stand with his back against a wall. Build threat as fast as possible, healing threat is an issue here. This is a good place to use cds/trinkets (elixirs if you must), we found them to be harder than the bosses. After 4 "Bog Lord Grows in Size" emotes, they were hitting the MT for 10k, and crit our priest for 43k!
