Need a custom head Gear item to Be removed from an NPC If shot in the head.

Basically I am working on something, and am creating some Custom head Gear for a new class of NPC Im going to add for my mod.

But It,s vital that the item be removed/destroyed/deleted from the NPC If he takes a head shot and ideally it should not be Equipable of visible in the NPC inventory to players.

does anybody know how this could be done pls ?

If I pull this off Great things will follow

wel you can make it non visible by screwing up the icons of it. and well for the removing... you would have to write a script that if the event handler damage is activated on hitpoint Head you item gets removed
