The Spirit Realm

I am trying to understand the relationship of our current top three poison dots. I have at present:

Nectar of Pain, level 70: 680 damage per tick for 660 mana, -30 resist adjustment

Nectar of Agony, level 74, 703 damage per tick for 683 mana, -30 resist adjustment

Vengeance of Ankhaul, level 75, 558 damage per tick for 742 mana, no resist adjustment.

I have Rank I of the 74 and 75 spells. I know that for Rank II and III the resist adjustment improves on both of them, and that the damage and mana cost on each increases (the damage per mana ratio remains the same). I know that the Nectar spells say that the damage decays over time, but Lucy apparently cannot parse exactly what that means, and I have not been able to see what the difference is, either.

It appears to me that Nectar of Pain (70) is a significantly more powerful spell than Vengeance of Ankhaul (75). It causes more damage, costs less mana, and lands more reliably. It appears to me that Nectar of Agony (74) is a small upgrade from Nectar of Pain (same efficiency, slightly higher damage, better resist adjustment at higher ranks); and that Vengeance of Ankhaul is a downgrade to both of them (lower damage, higher cost, equivalent resist adjustment only at Rank III).

So my question is, does anyone know how much the Nectar spells actually decrease in damage, per tick? And is Vengeance actually supposed to cause more damage, if all the spells run full term?

The Nectar spells are much better than Vengeance because they are resisted much less often. Even with a fully debuffed raid mob, Vengeance is resisted a fair amount of the time, where Nectar of Pain is one of my bread and butter dots, simply because it lands!

The necters do over time. You would need to drop anything that can focus the dot ticks if you wanted to parse it. They are known as reverse splurt dots (because necro splurt dots get stronger over time, sort of like the epic 1.0.)

You are right in thinking that the Vengeance of Ankhaul spell is shit compaired to the other 2. It is a really really poorly designed spell. I wont use it unless I solo.
