* To be able to sacrifice an item it must fit in the altar. If you are sacrificing to get rid of the item you can try using a [[trash heap]].
* Sacrificing creatures is done with a [[sacrificial knife]].
** This can only be done when there is a current mission for it, or, for a limited list of animals, also outside missions.
* Sacrificing 10 items one at a time will give the same amount of favor or deed Faith bonus as sacrificing all 10 at once. The items are registered individually and not as part of a unit. Combined items also generally give the same favor and bonus, except in the case of favor gain for alchemy ingredients for Libila and Nahjo.
* For low-value items, there is a minimum amount the Get Price value will contribute. For example, a 20QL tar will provide the same favor or deed Faith bonus as a 40QL tar.
