Last week we covered invisibility. Today we are going to continue the discussion of stealth magic. You’ll recall that for the invisibility spell we used an image of a clumsy mage making enough noise to render his invisibility meaningless (just because drawing invisible things is no fun). Today’s spell solves that problem by emitting a powerful anti-sound when a loud sound is detected.
We will use principles of anti-sound and anti-decibels from the Tome of Light and Sound to construct the spell and assume it is an encharge on our mage’s hat, making it “in” (normal) power level with a 16 DoP limit. For the sake of simplicity, we will also assume only Spell Casting I so any mage can cast it.
Ros (Stealth Radius): chaos(indireect), wind(indirect)
Zo (Negativity Arc) x 12 (Twelve)
Ros (Stealth Radius)
Saying “wa bi liu.”
This means that when triggered the encharged hat will discharge a 12d6*5 anti-decibel anti-sound, on average 42 dB. This is enough to reduce a shouting level sound (70 dB) below a whisper. It is also enough to reduce likely permanently deafening sounds to only temporarily deafening sounds. The wind (indirect) finger allows the spell to target a sound within 8 ft of the hat and put the center of its sound there. The chaos (indirect) means that spell will emit anti-sound over an area for more effective sound reduction.
Variations of this kind of spell can be used to muffle sounds in an area, such as silencing a group of arguing allies. It can also be used to muffle a number of sounds over time using a charge limited encharge, useful for passing silently by muffling the sound of foot steps.
Any spells you would like to see implemented in the Mind Weave spell system? Details for a one of the muffle variants maybe? Suggest them below and we might get to them on a later Saturday.
