General Information

Welcome to our World of Warcraft encounter guide for Mistress Sassz'ine in Tomb of Sargeras. We will teach you everything you need to know to defeat the boss in every difficulty.

On this particular page, we will give you a short overview of the fight as well as a list of things to watch out for (include LFR tips when applicable).

The other pages of our Mistress Sassz'ine guide can be accessed from the table of contents on the right.

To make it easy to navigate the guide, we have split it into 3 pages:

• Abilities: read about the encounter abilities;
• Normal/Heroic Strategy/Tactics: find out how to defeat the encounter in Normal and Heroic modes;
• Mythic Strategy: learn how to handle the new mechanics and increased difficulty of Mythic mode.

Mistress Sassz'ine is a 3-phase encounter that focuses primarily on environmental mechanics. Good cleave damage is an asset for dealing with the consistent waves of adds present during the encounter. Raid damage throughout the fight is quite high, and groups with potent throughput healing will find much greater success.

Here is a preview of the LFR difficulty from the PTR:

• Pick up Abyss Stalkers that spawn throughout the fight.

• Prepare cooldowns for high movement/pressure moments in the fight, such as Hydra Shots, or when several Burden of Pain debuffs are active.

• Quickly eliminate Abyss Stalkers and Razorjaw Waverunners.

• Avoid Sarukel's Devouring Maw and Vellius' deadly charge.
• Avoid standing in Concealing Murk, and position so that a Concealing Murk is between you and the Slicing Tornados, as the pool will consume the tornado and allow you to escape to safety.
• Carry Befouling Ink to Sarukel to make him go away.
• Players with Consuming Hunger should stand in Thundering Shock to detach the murlocs and make them vulnerable.

Bloodlust usage for this encounter is extremely flexible, and can be adjusted to suit the raid's needs. Using Bloodlust at the beginning of Phase Three can be helpful for quickly finishing the fight, as this is the longest phase and raid damage is at its highest. Alternatively, it can be used on the opener for maximum damage efficiency, as everyone's cooldowns and trinkets should be available.
