This fine powder appears like any other dust unless a careful examination is conducted. This will reveal it to be a very fine, very light, metallic dust. A single handful of this substance flung into the air will coat all objects, making them visible even if they are invisible, out of phase, astral, or ethereal. Note that the dust will also reveal mirror images and projected images for what they are, and it likewise negates the effects of cloaks of displacement or elvenkind and robes of blending.

This dust looks just like dust of appearance, and it is typically stored in the same manner and quantity. All things touched by it reflect and bend light of all sorts (infrared and ultraviolet included), becoming invisible. Dust of appearance reveals people and objects made invisible by dust of disappearance. Invisibility bestowed by the dust lasts for 2d10 minutes. Unlike the invisibility spell, dust of disappearance remains effective even after an attack is made. When applied to objects too big to be made invisible it may still affect a portion, such as making the ground look like it has a bald spot. It cannot make “windows” in walls, etc.

Starting Price: 120 gp 1 pellet
Pouch: Action
Duration: Special
Dust: 2 lbs.
Uses: 1d6+4 pinches
AoE: 5-foot cube of water
This special dust has many uses. If a pinch is cast into a cubic yard of water, the liquid is instantly transformed to nothingness, and the dust pinch becomes a marble-sized pellet, floating or resting where it was cast. If this pellet is hurled down, it breaks and releases the same volume of water. When the dust is sprinkled over an area (such as with a wave of the arm), it dries up as much as 15 cubic feet of water. The dust affects only water (whether fresh, salt, brackish, or alkaline), not other liquids. If the dust is employed against a water elemental or similar creature, the creature must make a Constitution save DC 12 or be destroyed. A successful save still inflicts 5d6 points of damage upon the water-creature. A pouch of this dust contains 1d6+4 pinches.
This unremarkable powder resembles chalk dust or powdered graphite—unless it is stared at. Stare at it and the dust changes color and form. Put a pinch of dust of illusion on a creature and the creature appears to become any other creature of similar shape, with a size variance of 50% (plus or minus) from the actual size of the affected creature. Thus, a halfling could appear as a human of small stature, a human as an ogre, a pegasus as a mule, etc. An unwilling recipient is allowed an Intelligence saving throw DC 15 to escape the effect. The individual who sprinkles the magical dust must envision the illusion desired as the powder is shaken over the subject creature. The illusionary power lasts for 1d6+6 hours unless otherwise dispelled. A typical pouch of this dust contains 1d10+10 pinches of the substance.
