@kozm0naut: Go

I suppose you could make a trigger for it.

• EVENT - Unit picks up item
• CONDITION - Item being manipulated equal to [Your item name]
• ACTION - Add [Ability] for [Triggering Unit]

And another for when he drops it.

• EVENT - Unit drops an item
• CONDITION - Item being manipulated equal to [Your item name]
• ACTION - Remove [Ability] for [Triggering Unit]

I'm not sure if this event exists but there must be something like it, maybe: A unit manipulates an item
