Easy one: Desecrate

[incognito]

Can you cast it on yourself, or something you are holding?

Lemme crack my PHB here...

Welll...the spell description doesn't seem to imply that it can be centered on an object or creature, so my gut says 'no.'

I suppose you could craft a wondrous item with Desecrate though. I seem to remember an item that has that effect, but I can't remember what it is, or in which book.

Two rings with Desecrate spell:

Desecration, Lesser: The ring of lesser desecration is a silver band that seems plain at first glance, but when a viewer peers closely at it, the viewer can see a faint decorative etching of writhing tentacles or other things that disgust or terrify the viewer (if good) or thrill the viewer (if evil). Three times per day, the wearer can speak a command word to imbue an area with a desecrate spell (duration is 6 hours).

Caster Level: 3rd; Prerequisites: Forge Ring, unholy aura; Market Price: 4,395 gp; Weight: --.

Desecration, Greater: The ring of greater desecration is a platinum band that appears simple at first glance, but when a viewer peers closely at it, the viewer can see a faint decorative etching of writhing tentacles or other things that disgust or terrify the viewer (if good) or thrill the viewer (if evil). The wearer is continually at the center of the effect of a desecrate spell.

Caster Level: 3rd; Prerequisites: Forge Ring, unholy aura; Market Price: 24,025 gp; Weight: --.


Now, I'm pretty sure that "unholy aura" was supposed to be "desecrate", because the other two rings listed were the ones that used Unholy Aura. Also, the caster level...

So the Lesser one desecrates a specific area, the greater one has a moving field that is always on.
