OnAcquireItem event
From NWNWiki
The OnAcquireItem event is fired when a Player Character or creature has an item added to its inventory.
The script attached to this event fires when an item is acquired, and added to a creatures's inventory. The item can be tested against a list of items, and if the item is found, an event could occur.
The OnAcquireItem event also fires whenever the OnClientEnter script would fire for a PC.
The OnAcquireItem event fires before the OnClientEnter event starts, for all the items in the PC's inventory (including those equipped!)
