I'm an Elf, with the edge Keys to Success which allows me to pick up iron keys.

I attempt to steal an iron key and get this message:
"Your hands burn at the thought of touching a large iron key."


I can still kill him and pick the key up off the ground.

I'm going with as intended, but someone else can call me out if I'm wrong.

The helpfile specifies "may to some degree handle keys".

Stealing is not one of those degrees.
