Quest: How to use an item on a unit?

[Fung]

This is a very familiar quest type in WoW.

Player obtains X item from quest giver.
Quest requires player to use item X on unit Z.
Use item X on unit Z 10x to complete the quest.

I'm not sure the best way to do this. I've thought about giving the player an item and that grants an ability. Then using the ability on unit Z 10x completes the quest. If I'm going in the wrong direction please let me know.

Thanks

there are a lot of quest engines out there wich allow these kind of quests and others for example kill quests ...

try this ... its written in jass but very easy to use
