Hi, people
Once again here to discuss workings of a spell because it came up in a game of ours. Would appreciate input or official rulling that we might have missed on the matters. I will try to limit the post to just the essential questions and I will number them. You are VERY welcome to answer in the same fashion, allowing you to pick the questions you know answers to - thanks
First a few facts. Barrier Sight basically allows the Mage to see through barriers consisting of different materials. Base spell is wood, scaling option sare: stone, iron, metal and for +10 points any substance at all. the initial depth is 1" per rank, but can be scaled up substantially. The spell's target is the caster (NOT a particular barrier) and the literal wording in the spell description says "see through barriers" and "may see through 1" of wood for every spell rank". This technically implies that the caster is free to look through multiple different barriers during the duration of the spell and that the limit is just on the depth, but might not have been meant this way.
Here are the questions:
1) Does a scale to a certain material include the base material? Example: if I scale the spell to see through stone, can I now see through wood and stone?
2) Do the higher scales include the lower scales? Example: If I scale to metal, am I able to see through wood, stone and metal OR wood and metal OR just metal?
3) Since the spell allows the caster to see through "barriers" and is limited only by the depth of the material, does this mean that the caster can look through different barriers of appropriate material during the duration of the spell?
4) Does the spell allow the caster to see through multiple layers of appropriate material separated with air or other translucent material? Example: the house you want to look through has two layers of wood 5" thick each with a layer of isolating air separating the wooden layers by 4". Assuming your spell allows you to see through 12" of wood, can you see through the cumulative 10" of the wall, disregarding the 4" air isolation?
5) Does the word "barrier" in the spell mean an actual barrier (wall, hard cover, door) OR does the word barrier include any substance that interferes with sight (curtain, milk carton, pocket, shield, earth, human flesh)?
6.0) Can the caster specify the thickness of the material he wants to see through? Example 1: a thief picking a lock only wants to see through the first inch or even less of the metal of the lock, so that he can manipulate the visible internal mechanism of the lock. Example 2: you want to see through the metal door, but not through all the metal coins on the other side of the door. Example 3: You want to see something imbedded in a complex structure using the "any substance" scale, and you obviously don't want to see through the whole structure (operating an arrow head out of the body of a person; looking for an item in murky water; looking for brain in avg. american)
6.1) If the caster can specify the thickness of the material, can he change this specification while the spell is active? Example: A surgeon is looking through a human body to locate an arrow head, but he guessed the depth wrong and can now see through the body AND the arrow head, rendering it invisible. Does he have to recast the spell OR can he choose to see through less of the substance while the spell is active?
