An alcoholic rainstorm rapidly builds in a 20-foot-radius, 60-foot-tall cylinder centred on a point within range, releasing intoxicating vapours. When the rain begins, each creature in the area must succeed on a Constitution saving throw or gain 2 levels of drunkenness. For the duration, a creature must also make this saving throw when it enters the spell’s area for the first time on its turn or ends its turn there.
A creature with levels of drunkenness inflicted by this spell takes 1d10 poison damage per level of drunkenness it has at the start of each of its turns. When the spell ends, affected creatures immediately lose all levels of drunkenness inflicted by this spell.
