Spell: steal item from a selected hero

[ExMortis]

How to do it?
It would be a spell for a Thief/Rogue stealing a random item for an enemy unit or npc while the Thief is unnoticed.

event should be - a unit begins casting an ability
condition - spell being casted equals *your spell* and casting unit has the buff *wind walk*
actions :
First check if the targeted unit has anything in his inventory.
Make a random number, then give the casting unit an item that the spell target unit has in his (random number)th inventory slot (if he posesses nothing in that slot generate a new random number and do it again ,*use a loop for it*).
After your unit recieved the item, destroy the one that the target unit possesses.

Something like this could do the work.
I don't want to tell you exactly what to do and simply show you a finished trigger, think a bit.
