The tooltip for Devouring Plague states that “If this effect is reapplied, any remaining damage will be added to the new Devouring Plague”. The intention of this being so that you are not punished for insanity generation and to make sure that you do not over-cap it.
This is a great addition to Shadow Priests however does not work, and has not since pre-patch began.
e.g. My Devouring Plague currently tics for 1000 damage when I consume one 50 insanity charge (one cast). When I then consume two 50 insanity charges (two casts) it still tics for 1000 damage and does the exact same overall damage as the single charge.
Obviously, with this not working as intended, it needs to be fixed.
Fixed in what way? If i look at debuff tooltip when overwriting old devouring plague, its damage tick still says the same. This is terrible unless it’s a display issue.
Also did some target dummy testing using Skada. Reset meter and set to show damage totals, record values, reset and try the other way.
Not allowing plague stacking:
min 180
max 2001
average 836 <—
Plague stacking, always wait 100 insanity and cast twice:
min 230
max 2296
average 1057 <—
There is some margin of error and i casted plague maybe 10 times for each way, but if it really stacked the average damage tick should be roughly double because the debuff duration is not longer. There is only 1 GCD between 2 plague casts.
Unless you’re saying that tick frequency is increased? That is more difficult to test…
Casting DP twice will not make DP tick twice as hard, because while the tickrate stays the same, a tick is added to account for the time between the first cast and the second where (In the case of back to back DP) no damage was dealt.
A standard DP for me ticks twice for 855, and then has a hasted partial of 349 (20.45% haste) for 2059 total
Casting DP twice is 3 ticks of DP for 1209, and a hasted partial of 493 (20.45% haste) for 4120 total.
Within 5% margin for spell variance, that’s easily double.
Casting DP on a target will deal X amount of damage over N ticks + a hasted partial.
Casting DP on a target with Y amount of DP left will deal X+Y damage over N+1 ticks + partial.
