PTR 1.0.7 – New Unstable Anomaly (Wizard)

FYI, I tested Unstable Anomaly (UA) quite a bit on the PTR on softcore.  Note that it does work as advertised but depending on your mitigation and monster power setting, there is a lot going on during the time that you are taking fatal damage.  It also depends on what type of incoming damage is occurring.  DoT sort of damage and ones that stack can drastically change your survivability once UA is proc’d.  So say you are chain frozen, but taking damage from plagued or desecrator when UA is proc’d, it may save you for a very short period depending on the damage/your mitigation.  If you can’t get out of that situation, UA may proc but the 45% HP it returns may also disappear in an instant.
The following is what I posted on the PTR bug forum when another player had asked if it was clearing DoT effects.

I did further testing and had to turn off monster power completely to see what was happening during actual game play. Without monster power enabled, I can see that it is working as intended from me just standing and not doing anything (not normal unless you are stun locked in place like if you are cc’d by certain affixes). At higher settings and/or with less damage mitigation, there’s a lot happening within each second. Without Prismatic Armor, I had very little margin for error once UA proc’d (I first tested with Storm Armor/Shocking Aspect and then Energy Armor/Prismatic Armor. 

I have a minor amount of life regen which didn’t interfere much. I tested again on MP1 and during actual game play with Storm Armor, it looked like I died immediately after UA proc’d. But when I looked through my recording frame by frame, here is what I saw. 

I went from 46k (full health) to 33k in one second. I dropped down to 20k at 1.2 seconds and then 7k at 1.66 seconds. From 1.66 to 2 seconds, I stopped taking damage from the first cloud. I resumed taking damage from the next plume and was at 7.1k health at 2.17 seconds (some life regen tick). At this point (based on the amount of damage occurring, it was considered fatal). At 2.2 seconds, UA proc’d and the amount of health points I received was 16.4k. It should’ve been 20.7k (45% of max health) but I believe the DoT was still taking place. If the DoT is stacking at that point (like in this case, multiple pods releasing poison) and you aren’t able to get out of that situation quickly enough (stop taking/reducing damage, popping a health pot, grabbing a health globe, gaining life from regen/attacks, etc), the safety net will only be a brief reprieve. With Prismatic Armor, the margin of safety increases a lot. 

I’m not sure if the DoT not clearing once UA is proc’d is working as intended though (since in my case, that was still 4k of health lost). When I tested against a single Blazing Guardian, the DoT from the fire was steady and I received my 45% of maximum 20.7k health when UA proc’d.”

In other words, UA does give you a 2nd chance so long as you are playing within the limits of your characters gearing.  But you also can further increase your chances of survivability by playing and more importantly, reacting like you didn’t have it.
