Candles of Invocation are specially blessed and prayered tapers which are dedicated to the pantheon of gods of one of the nine alignments. 

The typical candle is not remarkable, but it will radiate magic if such is detected, and Good or Evil will be radiated also if appropriate. 

Simply burning the candle will generate a favorable aura for the individual so doing if the candle's alignment matches that of the character's. If burned by a cleric of the same alignment, the candle temporarily increases the cleric's level of experience by 2, allowing him or her to cast additional spells, and even normally unavailable spells, as if he or she were of the higher level, but only so long as the taper is aflame.

Any burning also allows the casting of a gate spell, the respondent being of the alignment of the candle, but the taper is immediately consumed in the process.

Each candle will burn for 4 hours. It is possible to extinguish the candle as any other, but it can be placed in a lantern or otherwise sheltered to protect it from drafts and other things which could put it out, without affecting its magical properties.
