Blood-Tainted Candle

Wondrous Item, Common, Consumable

The tiefling lights the candle, which burns with an emerald flame.  He places it on the table and backs away.  As he leans against the wall, the strange flame reverts to a mundane state.

"This will show us where the demon is hiding," he says with a smile, "unless it's hiding in me."

A blood-tainted candle will burn for one hour once lit.  When a fiend, undead creature, or aberration is within five feet of it, the flame will change from its normal color to bright green.  This flame will also glow green in the presence of creatures that bear an infernal or undead lineage, such as tieflings and cambions. The effect can penetrate most barriers, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.
