# Birds of a Feather: Beverage of the Month Club
Beverage of the Month Club causes a doorbell to ring and a full box or bottle of a ![[beverage.png|25]] <font color="A38851">Beverage</font> to appear. To make sure this is balanced, there is a drop rate and a one use per viewer per stream limit.
The math: when you redeem the trigger, there are two checks. The first check is about rarity of the drink.
Common: 64% rate (a little less than a 2 in 3 chance)
Uncommon: 30% rate (a little less than a 1 in 3 chance)
Rare: 5% rate (1 in 20 chance)
Ultra Rare: 1% rate (1 in 100 chance)
I chose the rates based on how powerful a beverage is and how difficult it is to procure, either in terms of craftability or raw cost if orderable. Beverages that are special and only found once in the house, e.g. Sly Alembic, are not in the table and cannot be rolled for.

# Worms of a Scale: Cat Spills Your Drink
(This redeem works even if I don't have a cat) Causes me to automatically lose a single serving of a common ![[beverage.png|25]] <font color="A38851">Beverage</font>, according to a rarity table. To make sure this is balanced, there is a drop rate and a one use per viewer per stream limit. Some items do not have a single serving available, e.g. Skinshuck mead, in which case I'd lose the whole bottle. Beverages that are special and only found once in the house, e.g. Sly Alembic, are not in the table and cannot be rolled for.
The first time this redeem plays each stream, House of the Rising Sun by The Animals plays. I used this as the source for the sheet music arrangement: [the house of the rising sun Sheet Music with Chords for Piano, Guitar, Bass guitar, Drum group & more instruments (Mixed Quintet) | MuseScore.com](https://musescore.com/user/5060416/scores/1448636)
The math: when you redeem the trigger, there are two rolls. The first roll is about rarity of the item to be destroyed. The second roll is about the specific item to be deleted.
If I have at least one item in the category, of every rarity, the odds are:
- Common: 64% rate (a little less than a 2 in 3 chance)
- Uncommon: 30% rate (a little less than a 1 in 3 chance)
- Rare: 5% rate (1 in 20 chance)
- Ultra Rare: 1% rate (1 in 100 chance)
If a rarity tier is missing items (e.g. no Rare-tier items in the game) it's not included in the rarity roll.
The math behind this uses weighted conditional probability. You can read more about the math here: More info about the math: [[1. Meta Note About Stream Redeems#The math behind destruction-based redeems:|Destruction redeem math]]

# How It Works
I have to have at least one eligible ![[beverage.png|25]] <font color="A38851">Beverage</font> for Cat Spills Your Drink to take away in order for both Beverage of the Month Club and Cat Spills Your Drink to be available as a redeem.
The first time this redeem plays, a cover of Barbie Girl by Aqua plays. I made the music file in MuseScore using this arrangement for the sheet music: [Barbie Girl Sheet Music with Chords for Piano (Solo) | MuseScore.com](https://musescore.com/user/3435661/scores/3264951)
The math: when you redeem the trigger, there are two checks. The first check is about rarity of the drink.
Common: 64% rate (a little less than a 2 in 3 chance)
Uncommon: 30% rate (a little less than a 1 in 3 chance)
Rare: 5% rate (1 in 20 chance)
Ultra Rare: 1% rate (1 in 100 chance)
If your drink isn't found in the house, another roll is made until you get a drink you can spill on me.
