A few of us were tired of seeing various skills constantly showing a lower crit rate, so we did a lot of testing and managed to pinpoint the issue. I have data specifically for 4 skills:
- Stalking Blastbones (Necromancer Grave Lord pet)
- Skeletal Arcanist (Necromancer Grave Lord pet)
- Burning (status effect)
- Concussion (status effect)
To verify this, I set Spell Crit to 101.9% (41.9% while fighting a test dummy below 25% health, and using the Necromancer passive with 6 Grave Lord abilities to gain 60% Spell Crit). As you can see, the 4 abilities I listed all managed to land non-crit hits, despite the crit chance being over 100%.
Finding exactly which source of crit was causing the issue took some more time and testing. Thanks
@wills43b14_ESO,
@GulmarAvocado,
@xxcurs3dxx, and
@jayfillet for all the help. What we eventually found was that if we remove the Light Armor passives (by wearing 4 pieces instead of 5) and again bring the crit rate to just over 100%, then everything works fine. Here is an example with no LIght Armor passives, and 100.9% crit chance. You can see that now every ability shows the correct 100% crit chance.
I suspect the other status effects are also affected, but did not specifically test them. I also have a strong suspicion that Sorcerer's Greater Storm Atronach is experiencing the same bug since it is always lower crit than other abilities, but it is more difficult to test conclusively on Sorcerer since they do not have a crit passive to reach 100%. I do not know if any stamina variants are affected, or if the Medium Armor Weapon Crit passive works for Blighted Blastbones, Skeletal Archer and Poisoned status effect, someone else will have to test those.
If anyone is curious, we also checked the Precise weapon trait, various armor sets including Mother's Sorrow, the Spell Precision Champion Point, the base character 10% spell crit, and Major Prophecy (from Inner Light, potions, or both), and all of these sources seem to be working correctly. It is just the 10% Spell Crit from Light Armor Prodigy that is bugged.
