Bopper 2733 Posted February 14, 2020 Share Posted February 14, 2020 (edited) Interface Damage over Time (DoT) Procs How to Quantify Their Effects by Bopper Written: 14 February 2020 Last updated: N/A Some quick news. The bug causing Interface DoT procs to under-perform has been found and a fix should be easy enough to implement and hopefully will go live soon. With that being said, I wanted to put together a quick guide (or crib sheet, really) that details how you should quantify the effects of the Interface DoTs (once the bug is fixed, that is). This should help you decide if/which Interface DoT is right for your build. How do the Interface DoT procs work? The description of the Interfaces will read as “Adds… a Minor/Moderate DoT (X% chance) to most damaging attacks”. This phrasing causes some confusion as most assume this to mean there is an X% chance that each of your attacks will add 5 ticks of Damage over Time. In actuality, the Interface procs are mechanized such that each of the DoT ticks will have an X% chance to proc; however, once a tick misses all remaining DoT ticks are cancelled. This is what’s referred to as “Cancel-On-Miss”. How much damage do Interface DoT procs do? There are 5 Interfaces that offer a DoT proc: Cognitive (Minor Psionic), Degenerative (Minor Toxic), Reactive (Moderate Fire), Preemptive (Moderate Energy), and Spectral (Moderate Negative Energy). The Minor damage DoTs do up to 5 ticks of 10.71 damage each, and the Moderate damage DoTs do up to 5 ticks of 13.39 damage each (25% stronger than minor damage). Those numbers assume same level enemies (refer to Purple Patch mechanics if you’re considering fighting weaker/stronger enemies). What can I expect from a 25% DoT proc? This is the lowest performer of the bunch as it is very likely to miss on an early damage tick, resulting in all subsequent ticks to be cancelled. That being said, what is the expected performance? Probability and Expectation of Exactly X Ticks Proc'ing (25% DoT) X Prob(X) E[X] =X*Prob(X) 0 75.00% 0 1 18.75% 0.1875 2 4.69% 0.09375 3 1.17% 0.035156 4 0.29% 0.011719 5 0.10% 0.004883 Total 100% 0.333008 These numbers tell us that on average, each attack will do 0.333 ticks of damage. Given that a Minor DoT does 10.71 damage (Major DoT does 13.39 damage), this equates to averaging only 3.57 more damage per hit (or +4.46 damage, for Major DoT). What can I expect from a 50% DoT proc? This is the middle performer of the bunch and is only available as a Tier 3 Interface Proc. Below is its expected performance. Probability and Expectation of Exactly X Ticks Proc'ing (50% DoT) X Prob(X) E[X] =X*Prob(X) 0 50.00% 0 1 25.00% 0.2500 2 12.50% 0.2500 3 6.25% 0.1875 4 3.125% 0.1250 5 3.125% 0.15625 Total 100% 0.96875 These numbers tell us that on average, each attack will do 0.96875 ticks of damage, which equates to averaging +10.375 and +12.969 more damage for the Minor and Major DoTs, respectively. In this case, doubling our Proc probability nearly tripled out added damage performance. What can I expect from a 75% DoT proc? This is the top performer of the bunch and is only available as a Tier 3+ Interface Proc. Below is its expected performance. Probability and Expectation of Exactly X Ticks Proc'ing (75% DoT) X Prob(X) E[X] =X*Prob(X) 0 25.00% 0 1 18.75% 0.1875 2 14.06% 0.28125 3 10.55% 0.316406 4 7.91% 0.316406 5 23.73% 1.186523 Total 100% 2.288086 These numbers tell us that on average, each attack will do 2.288 ticks of damage, which equates to averaging +24.505 and +30.632 more damage for the Minor and Major DoTs, respectively. In this case, using a 75% DoT proc instead of a 25% DoT proc has increased the average DoT output by 587% (so nearly 7x damage). Using a 75% DoT proc instead of a 50% DoT proc increased the average DoT output by 136% (more than 2x damage). Can you show your work? Spoiler Gotcha! I will show my math later if folks really don't want to believe the numbers I just gave. Until then, be patient and I'll add numbers and formulas if you really need it.

Generator 207 Posted February 14, 2020 Share Posted February 14, 2020 If the damage ticks pull their cancel-on-miss tricks, will that impact any debuffs that are applied? Like, if Reactive stops ticking its Fire DOT, will that stop the -Res from applying? Thanks very much for doing the math on this. Link to post Share on other sites

I havent necessarily tested to monitor this, but when I was testing the 50% DoT proc, it had a 10% immobilize debuff proc too. Out of the 2,096 samples, I believe the immobilize proc'd about 9.6% of the time. So no impact.

underfyre 183 Posted July 29, 2020 Share Posted July 29, 2020 So some quick and dirty testing (as most of my "testing" is) is telling me that each ability (it does say "most damaging attacks") has a chance to independently trigger a proc, essentially adding a flat (2.288086 * 10.71 or 13.39) damage to each ability, which obviously favors low recharge abilities more than high recharge abilities.

It does. If you have a very fast set, something like Katana, you could leverage those fast attacks for heavy DoT stacking (I think up to 8 stacks, but seeing as how the DoTs only last about 4-5 seconds you wouldn't be hitting that anyways). Anyways, not only do you get a ton of DoTs, it also gives you more opportunity to apply debuffs as well. Debuffs last for 8.3s, so if you only have 25% chance to apply the debuff, you can likely keep a couple of debuff stacks (max 4 stacks) through the fast attacks applying more opportunities.
