Prestidigitation

Prestidigitation was an arcane cantrip. An older version of this spell was reversible and known as fumble-fingers.

Effects
When someone cast prestidigitation, he or she could choose from a wide variety of small, innocuous effects to occur within of the caster. Prestidigitation might allow a wizard to move an object of less than one pound, create a small sensory effect, clean or soil items no bigger than, light or snuff out a small light source, chill or warm a pound of non-living material, produce a small, fragile item, form an image out of nothingness, make a small mark or symbol appear on a surface for an hour or less.

Older versions of this spell, in particular practiced by wu jen, gave the caster a chance to teleport small items (palm-sized or less) to any place on their person and was used to pickpocket and/or deposit items on someone else—replacing a fine gem with a fake stone, for example.

Fumble-fingers could be cast on a target creature up to away and, if successful, caused the victim to flub the next attempt that required dexterity, such as using a tool, reaching for an arrow or a knife, or performing a somatic gesture while casting a spell.

Components
The newer versions of prestidigitation only required somatic and verbal components to cast. The older, wu jen versions, also required a drop of oil to be rubbed on the fingertips. Fumble-fingers instead had the caster flick the drop of oil toward the intended target.

History
The later versions of this spell could be cast as many times as the caster desired, but only a maximum of three "continuous" effects could be active at a time. Earlier spellcasting traditions had limits on how many cantrips could be held in the mind at one time.
