The art of making this rose-colored gas is lost in antiquity.
Usually found in FRAGILE glass globes or small metal vials, the mist
wafts out when released to form a spherical cloud. The diameter of
this cloud varies from 15 to 45 feet depending upon the amount of
gas. The vapors are heavy, and will remain in this volume for 1-4
days in dead air; they will drift very slowly with any air currents
(typically ½” per round). The vapors are damp and will cling to
clothing and skin.

Any human breathing the mist will writhe in pleasure for 1d6
rounds (1-3 rounds if saving throw vs. breath weapon is made),
oblivious to all surroundings. Affected persons will blissfully ignore
danger, and even physical attack will not rouse them. The mist closes
minds to all other stimuli, and thus rapture confers a temporary
immunity to magical attacks involving will force (such as Charm,
Magic Jar, Suggestion, et cetera). Unless restrained, those affected
will drop anything they carry and sink to the floor, twisting and
shuddering. Anyone in telepathic contact (or even psionic combat)
with a person breathing the mist will also be affected, for the same
duration. However, non-humans are immune to the vapors. During
the round after rapture has ended, movement will be slow (half
speed) and clumsy (no dexterity bonuses apply); such characters
never win initiative over more alert creatures, and are easily (1-5,
1d6) surprised.
