Purification: Ticks every 5s. We haven't found a way to avoid it. The damage seems to increase with time, and we haven't found a way to reset the damage. Combat Metrics reports it as Oblivion Damage and the icon is that of Oblivion Damage, but both are incorrect--the damage is NOT Oblivion and it IS possible to shield/mitigate it.

Meridia's Curse / Curse Expiry: The growing AoE that explodes with a stun. It's just an annoying burst of damage and stam drain from the CC break. You can shield/mitigate it.

Decrepify: The boss casts an ability with a 2.4s animation where it plunges all of its swords into the ground. At the end of this cast, every player except the tank will receive a 5s debuff called Decrepify. This debuff defiles the player and virtually zeros out healing received. It also applies an Oblivion Damage DoT that does 10% of your health damage per second. And it applies a mild snare and possibly other effects too. As far as we can tell, there is no way to prevent or avoid Decrepify.

Note that Curse Expiry and Decrepify are separate and unrelated. It is often the case that the two will line up and Decrepify will go out at the same time as the explosion, which is why we initially thought that the explosion was what applied Decrepify. But this is not the case, and the two are unrelated.

We initially though that vDoM HM was an unexpectedly easy HM, and it is, if all you want is to just clear HM. But as we are discovering, if your goal is to do HM deathless, it is actually pretty difficult, particularly if you get hit by a combo of these three things at around the same time.

It's possible that we're missing something here, and maybe there is a way to avoid what is apparently unavoidable. But if there is, we haven't found it yet.

If Combat Metrics reports it as Oblivion Damage, then the API reports it as Oblivion Damage. ¯\_(ツ)_/¯

I know. It's not CMX's fault because CMX just reports what the API reports.

There are instances, however, where the damage type actually encountered does not match the type of damage reported by the API, and this is one of them. I.e., the damage type reported by the API is not authoritative. Players still need to observe how the damage actually behaves in combat.

I agree. Though I somehow have the feeling this is not intended behaviour.

Are you sure the tank doesnt get defile ? when i tanked the hm, i did not get any health back through healing

After reviewing my event logs to verify that Decrepify doesn't hit the tank (it does not), I noticed something else: the Decrepify DoT is scaled off of your max health. Specifically, it does Oblivion Damage equal to 10% of your max health every second for the 5s duration of the effect.

In other words, Decrepify will do damage equal to 50% of your max health, and since you cannot mitigate, shield, or heal this damage, if the effect goes out when you are below 50% health, it's basically a slow-motion death sentence. Fun stuff.
