Trouble with Item definition

Ok so I have it set so if a specific unit picks up a item, it gives a penalty to stat points, however I can't seem to find the right condition.

Here's what I have...

E: Hero aquires a Item
C:
A: Subtract 10 Strength from hero

I've looked @ all the conditions and there's not one with "aquired" or "triggering" item I can use, it's all created or Item in region, which does me no good.

What should the condition do?

EDIT:
Anyway you are probably looking for Event Response - Item Being Manipulated.
It's right there with Last Created Item and the rest.
