I now understand that the gift basically makes you a cleric in terms of deity selection(via mordy), and that Toril isn't allowed for clerics(which I knew). I would ask for an exception to this rule if you have the gift of holy/unholy and are a Ranger or Druid so that they can consecrate alters to Toril(whom can otherwise not have alters consecrated).
I would keep the no clerics of Toril though as toril isn't technically a god, but having alters would still be nice.
If you wish to keep it the way it is, I would suggest adding a note to the gift of holy/unholy that it will not work with Toril and you will not be able to select Toril as a diety for nature based characters if you select the gift of holy/unholy on a nature character.
