Viscidus is a boss in the Temple of Ahn’Qiraj, one of the original vanilla raids. I know, a boss from there that can provide an issue?!

1. Viscidus is the second optional boss in Ahn'Qiraj and is a pretty unique fight. His Poison Bolt Volley does a lot of damage, so it's recommended to use Greater Nature Protection Potion s through the fight. This fight has 2 main phases, Freezing Phase and Shattering Phase. On the Freezing Phase, everyone must use Frost attacks to freeze Viscidus.
2. Sort, search and filter NPCs in World of Warcraft: Battle for Azeroth.

Viscidus is not necessarily a difficult boss, but MECHANICS! It’s split in two phases, which I’ll call FREEZING and SHATTERING, and I’ll give some class-specific details on each phase.

Viscidus is an optional boss in AQ40 which relies on having lots of frost attacks available. Traditional strategy is for mages and casters with frost wands to handle Phase 1. While melee and hunters sit outside the room to avoid damage. That works, but as a rogue it is boring.

Viscidus Fight Wow Won't Die

FREEZING

The first part of the boss requires you to freeze him. This requires you to hit Viscidus with 20 attacks that deal Frost damage. These classes have it easy:

• Death Knight: You have it very easy here. As Frost, a lot of your attacks will deal the Frost damage you need, and as other specs, you still have access to Frost abilities.
• Hunter: At level 100, use the Exotic Munitions talent, and use Frozen Ammo from that. You can also use Beast Mastery as your spec, and use a Chimaera. They have frost attacks!
• Mage: As a Frost Mage, you’re naturally very well equipped here. As Arcane and Fire, you still have access to some Frost-based abilities.
• Priest: Mind Spike deals Shadowfrost damage. Spam this until he’s frozen.
• Shaman: Frost Shock. Has a 6 second cooldown, so it may take a while!
• Warlock: Demonology is the way to go here. Touch of Chaos deals Chaos damage. Chaos damage is made up of all schools of magic, including Frost. Build up Demonic Fury, spam Touch of Chaos and Viscidus will eventually freeze.

Druids, Monks, Paladins, Rogues and Warriors have it a bit more difficult. With these classes it’s best to enchant their weapons with Enchant Weapon: Elemental Force then melee Viscidus until he freezes. The enchant won’t proc on every hit, so it may take a while.

SHATTERING

This part requires you to hit a frozen Viscidus 30 times before he defrosts. 30 hits, 30 seconds.

Here’s the easy classes!

• Death Knight: Army of the Dead. They’ll smash the bastard in no time!
• Hunter: The combination of you and a pet attacking will make short work of him. Stampede can also be a big help.
• Monk: Using two one-handed weapons means you will attack really quickly. Taking Summon Xuen as a talent will mean you can effectively attack twice as fast, as there’s two of you.
• Warlock: ’cause you’d be Demonology, the combination of you meleeing and a Felguard would likely make short work of Viscidus. Use Grimoire of Service to summon a second Felguard temporarily to ensure the kill.

Viscidus Won T Die

For other classes, to trivialise this fight, you need to have a Lumber Yard! You’ll eventually get a quest from it that allows you to get a trinket called the Barov Lumberjack Caller. Using this will summon a number of lumberjacks to fight for you, as thus:

Viscidus Wow Classic Guide

The combination of 5 lumberjacks and you meleeing the boss will make Viscidus smash to pieces in no time! Make sure you’re equipped with fast weapons, such as daggers or one-handed swords. Warriors swinging around giant two-handed battle axes may well struggle immensely here!

Abilities that summon meleeing minions are always helpful here. Paladins should throw out Guardian of Ancient Kings, and Priests should use their Shadowfiend, for example. Warlocks should favour summoning their Infernal/Abyssal over a Doomguard/Terrorguard, as the former does melee attacks and so would contribute to the shattering.

Viscidus Consumables

Why even go for this boss? Well, of course he drops a battle pet, the Viscidus Globule, required for the first Raiding with Leashes achievement! Good luck!
