If you're talking about the card Hireling, it says that it allows you to use an Item you otherwise could not. Essentially, the Hireling is a Cheat! card with a +1 bonus that you can discard to escape from the Monsters. So, in the case you provided, a Cleric with Hireling could give the Hireling the Kneepads of Allure so that the Cleric could use it.
