A common plant which grows best in temperate regions, dried and smoked in a pipe. A favorite of wizards for its calming effect, but popular among many classes and regions.
Effects
Advantage on concentration saves, ritual spells only take 5 extra minutes; lasts 4 hours.
Addiction
Upon each dose roll for an addiction saving throw, Wisdom vs DC5 + number of doses previously not resisted (max 10) to resist. Upon each long rest, roll for an addiction saving throw, identical to above; success removes 1 DC from the next addiction save, no penalty for failure.
DC 5-7 – disadvantage on concentration and not able to cast rituals if not consumed at least once in the last 24 hours.
DC 8-14 – effects only last 3 hours, disadvantage on concentration and not able to cast rituals if not consumed at least once in the last 12 hours.
DC 15 – effects last only 2 hours, disadvantage on concentration and not able to cast rituals if not consumed at least once in the last 6 hours, and permanent disadvantage against disease even once addiction ends; this effect can be cured though Greater Restoration or similar spell.
