Re-Vamped Spells: Invisibility

Another spell altered to fit in better with ideas about conceptual magic: invisibility.

Causes light to pass through the spellcaster to conceal their position until some action reveals it.


  • This is similar to but not quite an illusion. As long as there is no physical contact or visible movement, the caster can remain invisible for a long time.
  • If the caster touches or attacks someone, throws a dagger, or even bumps into a chair or opens a door, this reveals the caster’s position and ends the spell.
  • Anything worn or carried when the spell is cast is also made invisible, but only as long as the caster continues to wear or carry it. Throwing, dropping, or putting down an item makes the item and the caster visible.
  • Other actions can reveal the caster’s location as well. For example, lighting a torch. flapping a fan to create a gust of air. Basically, anything that alters light or the environment around the caster ends the effect.
  • Following from that principle: Food carried at the time the spell is cast becomes invisible, but eating it and causing it to be digested alters the food and the spellcaster, ending the spell.
  • Sound, smell, or vibrations don’t automatically reveal location, but high Intelligence or Wisdom characters have a 5+ on 1d6 chance of figuring out a location and can try to grab or attack the caster. Creatures with sharp senses also get a chance to find invisible targets, or automatically spot them if their hit dice are higher than the caster’s level.
  • Creatures that don’t use vision at all, or can operate completely without vision, ignore invisibility. However, there may be alternative ways to conceal odor or sound, eliminating that as a means of detection.
  • A successful attack on an invisible being, even one that does no damage like throwing a bucket of water in their direction, will end the invisibility.

  1. This series is making for interesting reading. So, am I understanding this correctly in that the person cannot move and remain invisible?

    1. They remain invisible while moving until they bump into something, open a door, move an object, or attack. If they avoid doing these things, they can move slowly with little or no risk of discovery. If they move quickly, a few characters may notice the rustle of clothing, the clink of metal armor or gear, the sound of footsteps, or movement of air as they pass by (high Int/Wis or out of the ordinary senses give 5+ on 1d6 chance.)

      I hope that's clearer!

  2. Following from that principle: Food carried at the time the spell is cast becomes invisible, but eating it and causing it to be digested alters the food and the spellcaster, ending the spell.

    This seems a bit difficult to justify, IMHO.

    Example 1: I have an M&M in my hand. I cast Invisibility.
    If I understand this correctly, if I put the M&M in my mouth, the spell is broken. What if I put it in my ear? my nose?

    Example 2: I have a nice meal with wine and dessert. 15 minutes after the end of the meal, I cast Invisibility. Does the process of "digesting" the meal makes it fail? Instantly? after... how long?

    What if have a dagger in a scabbard... I take it out to prepare to attack someone or for whatever reason. What happens to the spell? What if I am wearing a hood and I remove it while being invisible? Or I take off a ring while still holding it in my hand?

    1. Example 1: Invisibility doesn't end when you put the M&M in your mouth. It ends when it reaches your stomach and starts to transform.

      Example 2: Similarly, the meal is already being transformed when invisibility is cast, so it doesn't make you visible until you have to ... well, eliminate what's left over.

      The dagger, hood, and ring, and yourself, remain invisible until you let go of them, per the third point.

      You may want to explore what I mean by "conceptual magic". I did some posts on this, but didn't link them. Here's a link to the last of the conceptual magic posts, which has a list of previous posts in the series.
