This is a unique circumstance inquiry, only valid for those who have built a church in a cabin, or multi-leveled structure.

1) The Area of Influence for a Church is 20x20, centered on the Altar. Does this area only effect the horizontal plane?

2) If the altar were placed on a second/third/fourth(whatkindalarpisthis), would the area of influence then become 20x20x20?

The rules.

SFB - 2.3 - 2018 edition
Church
Pre-requisite: Occupation at 12th Level and at least one 9th Level Lightweaver Ability
At the 12th level, the Lightweaver may construct a truly Holy Church devoted to their God. The Church is a 20 foot square centered around the Holy Altar. It must be properly phys-repped with great care and excellent props. The Church will grant the following powers:
The Holy Altar is now indestructible. The Church may be destroyed by physically removing or destroying the majority of the holy items, trappings, and vestments that make up the church. This will include things like flipping tables, tearing down banners, breaking candles and pews, etc. Note that these items should only be destroyed in game; you can never destroy anyone’s property out of game without their permission. The phys-reps should be removed or moved in such a way that it is clear that the Church has been ransacked. If the Church is destroyed, the Holy Altar will once again become destructible.

The Lightweaver may decide whether the area inside Church is considered to be in day time (6 AM to 6 PM) or night time (6 PM to 6 AM) at all times by performing a 10 minute Rite involving lighting or extinguishing candles. This may be done at will.

Rituals cast within the Church receive an additional ‘Bless’ stone to the ritual bag. This Bless Stone should be uniquely coloured to distinguish it from all other stones. If the Bless Stone is pulled, it is put aside and another stone is pulled. If pulled, the Bless Stone will grant a bonus effect based on the God

served and the ritual cast, as determined by a Shaper or Ritual Marshal, regardless of whether the ritual succeeds or fails. A backlash roll might be turned into a flaw instead, a daily use might become two uses per day, the duration of the ritual may be extended, all who are involved in the ritual may receive a Shield Magic, and so on.
If a person within the Church has a Light Bless of any God and they are struck by a Dark or Draconic spell, the Bless will act as a Shield Magic and be expended. If the Lightweaver is struck by a Dark or Draconic spell and they have a Bless, it will function like a Reflect Magic and be expended.

Sacred Vessels from other Lightweavers may be created on the Holy Altar, even if the God the other Lightweaver follows is different. Sacred Vessels created in this manner will only function for the owner of the Church. The Sacred Vessel will still be considered to belong to its creator, but only the Church’s Lightweaver will be able to access the stored spells.

Depending on the quality of the Church’s props and the roleplay of the Lightweaver and their followers, Shapers may grant additional powers in special circumstances. Any powers granted will be tailored to the God and situation in question. These powers will only function within the Church. These ‘miracles’ will vary in power and effect and should be gauged by the size and power of the Church, as well as the average power level of the Guild the Church exists in. Examples of miracles include a small healing aura in a Church of Cassandra or a field which makes elves immune to Sense calls in a Church of Ll'yandra.
