The Luck Incense (Japanese: こううんのおこう Good Luck Incense) is a type of held item introduced in Generation IV. It is an incense that allows Chansey and Blissey to produce Happiny Eggs. In battle, its effect is identical to the Amulet Coin.
The Luck Incense doubles the amount of prize money received after battle if the holder takes part in the battle. It also doubles the amount of coins picked up from Pay Day.
Luck Incense does not stack with Amulet Coin or other Luck Incenses; however, it does stack with Happy Hour and Prize Money Power.
Once the Pokémon has participated in battle while holding it, it takes effect; it is unaffected by Klutz and takes effect even if the holding Pokémon faints or the Luck Incense is removed or negated.
If held by either parent of a pairing in Pokémon Day Care or the Pokémon Nursery that would produce a Chansey Egg, a Happiny Egg is produced instead.
