POE 2 - Hrimnor's Hymn Aftershocks doing no damage.

Got Hrimnor's Hymn to drop in the Grelwood for my new warrior character, but the aftershocks on using Rolling Slam with the unique did zero damage against bosses and normal mobs. Unsure if it works with other slam skills or not.

I find aftershocks in general are doing no damage.

Deleted previous post because it was kinda misinforming, edited version:

Rn i can test it only between Earthquake and Rolling Slam. Rolling slam never transfers damage to aftershock, so that interaction does not work. With Earthquake aftershock works correctly, but only after first explosion hit at least one target. If first exlosion misses, then aftershock does not damage anyone, even if enemies walked into the range.
