Immortep Exceeds Expectation

I ran the Boss3 test on Immortep.  Like Vlad, I think Immo can trigger a proc if the only energy reduction on the boss is him with Scatter 4.  So I added my HQ to the lineup to make sure that doesn't happen.

Here's the setup:

Immo not evo.

Immo has on Bulwark crests, but you can't see that.  HQ has Berserk.  Neither of these should chance the test result more than a tiny amount.

And here's the outcome:

Better than Vlad!

106022552 damage. My earlier test of just PD+HQ got 64953661 damage. So we can see the delta from adding Immo is 41068891 damage. Immo has 1000ms attack speed, so as in the previous tests, I model his ramp-up as 5 seconds of nothing followed by full damage. So, 175s. We find the number of hits by dividing by 35000: that's ~1173.4 hits.

In 175s, there should be 875 auto-hits. So, we find ~298.4 hits from procs. According to the wikia article on Immo, he procs every 5 seconds, so we estimate 35 procs during the run. Thus, he's hitting ~8.53 times per proc.

The wikia article says that Immo's proc pulses every 0.2s, for "just under 5 seconds", with a 20% chance per pulse to hit. Taking "just under 5" as 4.8, that works out to 4.8 hits per proc.  Incorrect!  4.8 HPS is clearly ruled out by my test.

My test shows a roughly 35.5% chance to hit each pulse (assuming pulses of 200ms, and 24 pulses).  This is unexpected.  On the other hand, since the wikia is already claiming that Immo's in-game description is wrong for the duration of Sandstorm, it's not too shocking that we might have the percentage wrong too.  (Where did the asserted 20% come from?)

I plan to re-run the test tomorrow.  At the least I can replicate the result, and verify visually that Immo is continually proccing (as the wikia article suggests should happen).

Update: here's another run.  Same setup and double checked for nothing wrong.

Ditto.

105959354 damage.  That is .05% less damage than before, that is, basically indistinguishable from the earlier run.  I did watch it carefully, and I can verify two things asserted at the wiki.  First, the proc really is 5 seconds.  Second, there really is a brief gap where it's not on.  That might be a graphical glitch or it might not, but you can certainly see it.

Anyway, the conclusion stands.  At max speed, Immo hits substantially more than he has gotten credit for.
