If you have both instant cast Corruption and Unstable Affliction, and you cast them together, which should you cast first?
Here’s the visual. On top is Unstable Affliction followed by instant cast Corruption. The bottom pair shows instant cast Corruption followed by Unstable Affliction.
Notice that the only real difference is when the first dot hits and when the last dot hits.
Here’s a graph of total damage done.
Corr/UA comes out early in the lead and applies its first dot at 3 seconds.
But at 4.5 seconds UA/Corr becomes superior by applying both dots at once.
From 4.5 seconds to 19.5 seconds the two methods swing back and forth in superiority. Each is superior for 50% of the time.
From 19.5 seconds to 21 seconds UA/Corr is superior in that it applies it’s last dot first.
At 21+ seconds (assuming no reapplication) the order is irrelevant, they have done identical damage.
So the answer is.. it doesn’t really matter.
Personally I prefer UA/Corr. I can see/hear the 1.5 second cast time of UA and use that to tell me when to hit Corruption.
