Gravebind interaction seems inconsistent.

Testing Gravebind with a friend.

Does NOT trigger herald of ice or ash currently.

Does trigger herald of lightning and purity.

Gravebind: "Nearby enemies killed by anyone count as being killed by you instead"

Herald of Ice: I assume this is not proccing because of the shatter requirement, but I would argue that Gravebind should count as you shattering the enemy.

Shatter: "Non-unique enemies that are killed while frozen shatter into pieces"

The party member kills a frozen unit, the Gravebind player gets the kill credit, therefore should shatter the enemy.

Herald of Ash: This looks like its not proccing because of the overkill requirement. This I can see as understandable as it is not the Gravebind players damage.

Thoughts?

Adding to this Tulborn grants the user power charges. So it counts as you killing a frozen enemy but for some reason doesn't give the shatter
