Artifact offhand feature bug

smulch

The Control Wizard artifact off hand feature for Storm Spell is currently bugged in multiple ways.

First, having that feature makes storm spell lost its 100% crit chance for some reason. It looks like about 15% of the storm spell procs have a chance to roll "normally". Meaning that it can crit or not crit. I say that because I have about 60% overall crit chance and I usually get 91% of my flanking storm spell procs as crits. If 15% of those procs have to roll for crit chance, then it means that 85% of them are 100% crit chance and the remaining 15% at 50% crit chance should bump it to 92%, which is what ACT reports for me.


Secondly, it makes a lot of storm spell hits just deal 0 damage. Somewhere close to 15% of the storm spell procs will do 0 damage, which is pretty close to what should be the frequency of extra storm spells because of that extra 5% (30/35 = 85,71%).

Switching the off hand feature to something else fixed both of these issues so I,m 100% certain the problems come from this.

I can provide ACT logs if you need them.

I can concur. Two odd behaviors are occuring. ACT will record a "No damage" hit of Spell Storm. That doesn't actually appear in the combat log, so it might be an ACT issue.

However, it looks like the off hand feature is actually a 5% chance to proc Storm Spell on ANY hit, not just critical hits. So when you slot the feature, if you get a bonus proc of Storm Spell on a non critical hit, the proc won't crit either.

Whether or not that's the intended behavior is up to the Devs to decide.

what is actually happening is that the offhand feature for storm spell is allowing storm spell to proc on non critical hits from damaging spells via the 5% chance bonus. I have replicated this issue over 3 hours of testing today repeatedly. So confirmed, Ironzerg, nice catch

Ok, I've done some more in depth testing.

I've done two tests of training dummies testing of 16 minutes each. The only spell used was ray of frost and it was non stop channeling.

First test is without the storm spell feature and the second is with.

On the test without, I've had a total of 1728 ray of frost ticks of which 848 were critical strikes (49% crit rate).
I've had 310 storm spell procs (36,55% proc rate). 100% of the storm spell procs were critical strikes.



Second test is with the storm spell feature. The test was a little shorter due to having trouble making the mouse autocast but it's not by much.

I had 1597 ray of frost ticks and 3 arcane missile hit (accident but not relevant enough to alter the test). So 1600 hits. Out of those 1600 hits, 870 were critical hits (54,375% crit rate).
There was 579 registered storm spell procs. Out of those 579 procs (66,5% proc rate!), 132 did 0 damage. If you remove those bogus hits, it makes 447 storm spell procs (51,38% proc rate). Now, not all of the procs registered as critical strike. 71 of them registered as normal hits and is most likely caused by the off hand feature. If you extrapolate the average crit chance to this, it would mean that the 71 normal hits represent 43,625% of the hits, which would mean about 162 storm spell procs caused by the off hand feature. This would give 279 storm spell procs from the normal class feature and 162 from the artifact off hand feature.

What it means is that the off hand features do NOT alter the way storm spell act on its own (you won't lose damage) but the numbers I'm getting are very odd.

There might still be a bug going on with it which make it stronger than it's supposed to be (unless I got one hell of a godly rng run).

Well, tomorrow all of my AD is going into Cubes of Augmentation, I think I need to unlock a certain artifact power XD
