Herald of Thunder and Critical Strike Chance

My English is not good so I used google translate.

I have a question about Herald of Thunder and Critical Strike Chance.

"Socketed Spells have +4% to Critical Strike Chance" can affect "Herald of Thunder".

Then I equipped "Herald of Thunder" on my helmet, "30% increased Critical Strike Chance for Spells"(Arcane Potency) can not affect "Herald of Thunder".

Why "+4% to Critical Strike Chance" can affect "Herald of Thunder" but "X% increased Critical Strike Chance for Spells" can't affect "Herald of Thunder".

"Herald of Thunder" is a spell or not a spell?

"X% increased Critical Strike Chance for Spells" not affect "Herald of Thunder" because "Herald of Thunder" does no deal spell damage? But I have "+4% to Critical Strike Chance".

"24% increased Global Critical Strike Chance"(Amulet)can affect "Herald of Thunder".

So only "X% increased Critical Strike Chance for Spells" of "Atlas Passive Skill Tree" does not affect "Herald of Thunder"?

It is a bug or someting?I don't know.

It is explained in the Interactions section under "secondary damage" on the Wiki page:

I find it a bit confusing, but it makes sense.

Herald of Thunder is a spell.

The lightning storm it creates does not deal Spell Damage, similar to the explosion created by Herald of Ice. Hits from the storm would not be considered a hit with a spell.

This is also similar to Detonate Dead. The spell Detonate Dead deals two hits at the same time: one is a Spell Hit dealing Spell Damage based on the Fire Damage displayed on the gem, while the other is not a Spell Hit, instead dealing Secondary Damage based on a percentage of the corpse's Max Life.

Modifiers to spell damage does not affect the Storm created by Herald of Thunder. This includes stats like "Critical Strike Chance for Spells", or the Shaper/Crusader ring prefixes granting "Gain Life per Enemy Hit with Spells", that affect Hits with Spells. It also includes the modifier "+% to Spell Critical Strike Chance" that can be found as a Corrupt implicit modifier on Gloves.

"Socketed Spells have +4% Critical Strike Chance" can affect it because the modifier it is adding is "+4% Critical Strike Chance", with the condition of "the Socketed Skill is a Spell". And again: Herald of Thunder is a spell.

Responding directly to this for clarity: the skill tree affects Herald of Thunder.

Stats that would only apply to Spell Hits (such as Critical Strike Chance for Spells) will not affect Herald of Thunder, whether they be on equipped gear or on your skill tree.

Thank you for your answer.Your answer is very helpful to me.

It means that skill nodes like "Arcane Potency" just affect skills with spell hits,right?And skill node "Ancestral Bond" affect all skills yourself.

Modifiers(+4% Critical Strike Chance,+X to Level of Socketed Spell Gems,Your Spells are disabled,X% increased Global Critical Strike Chance) on my equipped gear affect all spells,whether spells have spell hits.

I understand that now,thanks.
