[Papyrus] Any function/event combinations that work when you drop an item on an NPC

Hi there

I'm looking for a function/event which triggers when the player lets go of an item and that item collides with another actor.

I want to make a script which deals damage to an NPC when you drop an item on them and I wasn't sure whether there are any events/functions which allow this.

I was thinking of casting an invisible dummy damaging spell on the NPC when an object collides with them. Then scale the damage of that spell accourding to the weight of the item + the distance travelled to the actor. This might be interesting when you drop an heavy item from above on an NPC.

I won't mind if it requires SKSE.

Thanks in advance

Kind regards
