Rule Name:Shrinking
After an in-depth discussion about Shrinking, specifically concerning perception of a character with Shrinking, here are the official house rules. By fifth edition rules, a character with Shrinking is just as easy to see as someone without Shrinking, regardless of how many levels of Shrinking they buy. The primary purpose of the Shrinking power is to become smaller, not to serve as a limited form of invisibility.

Shrinking works as described in 5th ed. rules with the following qualifiers.

1. In most circumstances, a character with Shrinking is just as easy to see as a character without Shrinking. The PER modifiers to perceive a character with Shrinking come into play only when the character is using Stealth, Concealment or otherwise making an effort to remain hidden. The PER roll modifiers also come into play if a PER roll would be required to see a normal sized person in the same circumstances.

2. If a player creates a character with "many levels" of Shrinking and wants to indicate that this makes them so small that they are almost impossible to see under any circumstances, they should buy appropriate powers to simulate this (e.g., Invisibility) and then link it to Shrinking.

3. If a player creates a character with so many levels of Shrinking that they would normally be almost invisible, but does not buy other powers to reflect this, it is up to the player to indicate why their tiny character can be easily perceived. This should be based on the concept of the character. For example, someone who defines their Shrinking in a "Dimensional" framework, might create easily perceived "dimensional ripples" around him when he moves and the ripples are only suppressed under certain circumstances (e.g., using Stealth or Concealment to hide).

4. During the discussion, the Hero rule that states that a power must be perceivable by three senses came up regarding Shrinking. I plan to use some common sense for this and define the senses based on the special effect of the Shrinking. For example, a typical housecat has a couple of levels of Shrinking (0 END, Persistant, Always On, Inherent). The cat is not actively using Shrinking to make itself small. Small is it's natural state of being and that can be noted with just about any discriminatory sense. It is not otherwise necessary to define three senses that can determine that the cat is using the Shrinking power to attain its size. Conversely, as another example, a mutant has the ability to shrink down to housecat size. The power is not Always On, Inherent but is in a framework of "bioelectric powers". While the character is shrunk, someone with normal senses can simply see a 25 cm tall person and might assume that they are using Shrinking or might assume that 25cm is their normal size, whereas someone with, say, Discriminatory Radar Sense, might note that the character is using an active power. Basically, when you buy Shrinking, you will need to note whether certain sense groups might note something other than the simple fact that you are of a different size.

5. Another issue that came up during the discussion was Microscopic Vision. Does it negate any of the PER modifiers for Shrinking? I haven't found any rules that states that it does so, in general, it won't. However, if a character with Shrinking is using Concealment to hide, say, in a small crack in the wall, and a character with Microscopic Vision looks into the crack, I will probably negate some or all of the PER roll modifiers from Shrinking for the purpose of determining whether that person can see the hidden character.

6. There are a whole bunch of "what ifs" that could come up but I will deal with them on a case by case basis.
