Activation: Swift (mental)

Weight: —

This coin-sized crystal sphere is inscribed with arcane sigils representing earth, air, wind, fire, magic, death, and beauty. It rattles like soft thunder. As its name suggests, a witchlight reservoir can hold a small quantity of magical power, which can be used to enhance the power of a melee weapon. To imbue this augment crystal with power, you must directly expose it for 8 hours to one of the following substances: sunlight, moonlight, blood, or wine (at least one pint of either of the last two substances). Each one of these substances grants the item a different effect, as described below. Exposing a full reservoir to a new substance replaces the old effect with the new effect. When activated, a reservoir adds an extra effect to its weapon's next successful melee strike (as long as it is made before the end of your turn). The effect depends on the substance to which the witchlight reservoir was exposed (see above).

Sunlight: +2d6 fire damage (or +4d6 fire damage if the target is undead).

Moonlight: +2d6 electricity damage (or +4d6 electricity damage if the target is a lycanthrope).

Blood: +2d6 damage to a living target.

Wine: - 2 penalty on Will saves for 1 round.

A witchlight reservoir functions five times before it loses its power and must be imbued again. It is considered a greater augment crystal.
