Ambrosia

Ambrosia is a foodstuff that is only obtainable through the ambrosia sprout event or by trading.

It provides a +5 mood buff when eaten, as well as a hefty +50% to joy, but is slightly addictive.

It is classified as a drug in-game.

Addiction

Addiction to ambrosia is trivial compared to other drugs; it takes only 10 days before full recovery, and does not impair functioning; it only causes a -10 mood debuff as that pawn craves more ambrosia.

It is also somewhat rare to get an ambrosia addiction, as each fruit only has a 1% chance to give one.
