The deadly nightshade, another denizen of the swamps, was christened for its strange, waxen flowers, which only bloom at night. It should be carefully handled and prepared, for it is poisonous to the touch. For magical preparations, it is either crushed or brewed into a tea. As a reagent, nightshade focuses the powers of death, damage, poison and illusion. All forms of poison use nightshade in one way or another, and poisons are the most varied potions in Britannia. A weak poison potion is easy enough for anyone to make with a single nightshade. A hobbyist can produce a normal-strength poison potion with two nightshade, and a journeyman alchemist can use four nightshade to make a strong poison. Finally, a master alchemist is capable of producing the deadliest of poisons (save the touch of the poison elemental) using eight nightshade. Nightshade is used primarily in spells that are intended to cause death.
