Ale Slumber

The caster takes a mouthful of an alcoholic beverage and proceeds to spray it out, towards a creature of choice within 10ft, causing the alcohol to become plant spores which when inhaled, will cause a creature to fall asleep for one minute (or when roused by another creature or other affect that causes damage) on a failed con save. If the target succeeds a con save, they do not fall asleep and are immune to the spells affects for 24 hours.

Plants and creatures who do not breath automatically pass the save.

At Higher Levels: For every level above 2nd, the target is asleep for an additional hour.
