Ulduar Boss Parsing Rules

Last updated: January 25, 2023

This article will go through the various rules, banned items, and adds excluded from bosses in Ulduar on Warcraft Logs rankings.

If you have any suggestions or questions, please join us on Discord to discuss.

All Star Point Formula

With Hardmodes, we recognize the current ASP formula is lacking (from Sartharion testing).

The hardest Hard Mode for each fight + Algalon rewards from 120 - 240 All Star Points.

Downtime Removal

We have historically removed the downtime on some fights to not punish shorter kill times. Examples such as Reliquary of Souls in Black Temple had the downtime between boss phases removed. We are also implementing this on Phase 1 Razorscale, Mimiron intermissions, and General Vezax Hard Mode (from 5% boss health to spawn of Saronite Animus).

Boss Changes

As always, all trash mobs are excluded from boss parsing. All Hardmodes rank higher than lower difficulties.


Player 1 does 3k DPS on Hodir HM. Player 2 does 4k DPS on Hodir non-HM. Player 1 ranks higher as every HM parse ranks higher by default.

Flame Leviathan

This boss is removed from character pages, All Star Points etc. It is still included in boss speed.

Ignis the Furnace Master

Only the killing blow on Iron Construct (ID: 33121) counts for damage parses.


Only Damage Done to Razorscale counts for parses, and Phase 1 is counted as Downtime.

XT-002 Deconstructor

There are no adjustments on this boss, all damage and adds count.

The Assembly of Iron

Damage done to boss mobs before they heal up to full is excluded.

Damage done during Overwhelming Power is normalized.


Damage done to Rubble is excluded.

Damage done to Left Arm and Right Arm only counts if they die.


Damage done to Swarming Guardian is excluded.


There are no adjustments on this boss, all damage and adds count.


Phase 1 is removed, and only damage done to Thorim counts.


Damage done to Freya before her last overheal is excluded.


Downtime is removed during phase transitions.

General Vezax

On Hardmode only: Downtime and damage done between General Vezax reaching 5% health for the first time and Saronite Animus (ID: 33524) spawning is removed


There are no adjustments on this boss, all damage and adds count.


Damage done to Living Constellation and Dark Matter is excluded.


Externals Cap

On Retail, we've added an Externals Cap. This is also implemented for Power Infusion in Classic.

This means you will only be able to get Power Infusion from the equivalent of one priest. The number of externals received cannot exceed the number of which could be given to one individual by one partner. However, you may receive each buff from more than one player, so long as the number of buffs you receive remains under the cap.

Any parses that break these restrictions will not be ranked.

World Buffs

A majority of world buffs, such as:

and more are banned.

Battle Squawk / Battle Chicken

Battle Squawk from Battle Chicken is banned. This buff will invalidate your boss parse and complete raid parse.

Fishliver Oil, Light of Elune, and More

We are going to be stricter on one time use items such as Fishliver Oil and other quest items. These items are banned for parsing, but they are fine to use for progress guild ranks.


We have some other rules that invalidate logs.

Life Tap

Excessively life tapping to pad healing parses will invalidate your kill.
