This Spell has me pretty confused.

This spell functions as lesser planar ally, except that you entice a fey of 6 HD or fewer to lend you its aid with an offering of music or something else it finds appealing. Like lesser planar ally, this spell is unpredictable, and the fey who answers the calling is up to the whims of nature and the fey, not your own choice.
You must succeed at a Knowledge (nature) check or Perform check (DC = 20 + target's HD) in addition to the spell's material component to entice the fey into appearing, after which you can negotiate for the service and your payment. The maximum HD of fey that you can call with that casting is equal to the result of your check – 20. For example, if your check result is a 24, the maximum HD for the called fey is 4. A high result doesn't allow you to break the HD maximum for the spell, and a result of 20 or less means you can't call a fey at all. If the fey doesn't like the sound of your offer, it can simply choose to refuse, in which case you don't expend any of the material components for the spell, either the offerings or the payment.
I'm particularly confused by the last chunk concerning the perform or knowledge check. It says you have to make a check and the result -20 is the HD limit of what you can call. It also says that rolling 20 or fewer doesn't mean you can't call a fey at all. But then what DOES it mean? If the HD limit of what I can call is zero or a negative number, that seems like I can't call a fey at all. Does anyone have any thoughts on how to interpret this?
