Consumables

This page is in need of content. Opossum/Blender change makes things less complicated, but also requires this page to be adjusted. There is no decimal portion of consumable gains anymore, examples need to be fixed.

Overview

Consumables in KoL are computed thusly:

Each consumable has a minadv, and a maxadv. These two values are internal to the database. The player never sees these. Both minadv and maxadv are integers.

When a food or drink is consumed, the following happens:

1. The game chooses a value between minadv and maxadv in a uniformly random fashion.
2. Munchies pills bonus adventures are computed and added.
3. Salty Mouth gets added on, for applicable drinks.
4. Tuxedo shirt gets added on for applicable drinks.
5. Milk of magnesium and The Ode to Booze bonus adventures are added.
6. Ol' Scratch's salad fork and Frosty's frosty mug bonus adventures are computed and added.
7. Opossum and Blender bonus adventures are added, if applicable.

Size and Quality

Many consumables also have a Size (equal to the fullness/drunkenness of that item) and a Quality (value chosen to make adventure gains better). The S/Q paradigm denotes that a food uses Size and Quality to determine its minadv and maxadv. Most older (NS11) consumables follow S/Q. Size and Quality are very important for crafted consumables, when two craftable things are put together, the Size and Quality values of the two get added together.

For any consumables following S/Q:

• minadv=Size
• maxadv=Size*Quality

Range Chopping

For a Food, if the difference between minadv and maxadv is greater than 7, then a chop is performed from either end of the range. For a Booze, if the difference between minadv and maxadv is greater than 5, a chop is performed. This chop is equal to:

• Food: floor((maxadv-minadv-6)/2) from both sides.
• Booze: floor((maxadv-minadv-4)/2) from both sides.

Consequences

Because of this, a food that has been chopped will always have its unmodified observed range be 6 or 7, due to the following:

• T = top of range, B = bottom of range, M=max, m=min.
• T = M - floor((M-m-6)/2)
• B = m + floor((M-m-6)/2)

T - B = M - floor((M - m - 6)/2) - m - floor((M - m - 6)/2)

= M - m - floor(M) + m + 6

= [M - floor(M)] + 6

= 6 + (0 or 1)

Similarly, a booze that has been chopped will always have its unmodified observed range be 4 or 5.

What to take away from this: If a food's unmodified observed range is not 6 or 7, then either it has not been chopped, or the food has been messed with in some way by the game designers. Similar logic can be applied for a booze which has a range that is not 4 or 5.

Furthermore, if a food's unmodified observed range is less than 6, and the minimum of the range is not equal to the Size, then the food is messed with. Similarly for a booze's unmodified observed range being less than 4.

Other Consumables

There are also many consumables which do not follow the S/Q pattern. Supernova Champagne is an example. Its range is hardcoded 7-11.0. While that would fit with S=3, Q=5, it does not fit. These types of consumables are assumed to have their minadv and maxadv hardcoded.

Examples of Size and Quality

A Booze example

Size and Quality values are added together for craftable things. Basic booze has S=3 and Q=1, basic fruits have S=1 and Q=1, and cocktail garnishes have Q=3. Therefore, Advanced Cocktails are S=4 and Q=5. Their minadv is 4, and their maxadv is 20. They get chopped by floor(20-4-4)/2 = 6 from both sides, producing the range 10-14.0. So the minimum is 10, and the maximum is 14.0. With no modifiers, this means that all 5 observable values are equally likely to show up, and there will never be an adventure added.

A Food example

Hi meins are S=5 and Q=8.9. Their minadv is 5, and their maxadv is 44.5, they get chopped by floor(44.5-5-6)/2 = 16 from both sides, producing the range 21-28.5. So the minimum is 21, and the maximum is 28.5. With no modifiers, this means that the 8 observable values (21-28) are equally likely to show up. However, there is also a 0.25 probability (25% chance) that an additional adventure will get added on. So 21 will show up 3/32 of the time, 29 will appear 1/32 of the time, and 22-28 will each appear 1/8 of the time.

Modifiers

Munchies pills add adventures to Food in a tiered fashion. If the actual amount that the consumable would give you is in the following ranges, then that's how much Munchies pills will add.

• 1-3 adventures, +3
• 4-6 adventures, +2
• 7+ adventures, +1

Then Milk of magnesium and Ode to Booze are added on. Similar to Munchies Pills, Milk and Ode add adventures in tiers. If the actual amount that the consumable would give you is in the following ranges, then that's how much Milk or Ode will add.

• 1-4 adventures, +1
• 5-7 adventures, +2
• 8-10 adventures, +3
• 11+ adventures, +4

A consequence of this is that for a food like boring spaghetti, which has a range of 4-11, applying Milk of magnesium (with no other modifiers) can give it:

• +1 (if a 4 is rolled)
• +2 (if 5-7 are rolled)
• +3 (if 8-10 are rolled)
• +4 (if an 11 is rolled)

After that, for applicable beers, Salty Mouth gives a 4-6 adventure boost uniform-randomly.

Frosty's frosty mug increases adventures gained from booze by 30%, rounded down. If the booze is a beer, however, adventures are increased by 50%, also rounded down.

Ol' Scratch's salad fork increases adventures gained from food by 30%, rounded up. If the food is a salad, however, adventures are increased by 50%, also rounded up.

Finally, for applicable boozes, the Tuxedo shirt gives a 1-3 adventure boost uniform-randomly.

Example with Modifiers

This example will show how Superhuman Cocktails behave when modified by Ode and Frosty's Mug.

It may be easier to follow along with this example by looking at the table below, since sometimes it is not readily clear why the math works out the way it does.

Superhuman Cocktails are minadv 4, with maxadv 28. This means the chop is floor(28-4-4)/2 = 10. This means that the base range is 14-18.0. The average of this range is 16.0.

Applying Ode to this increases all values of this chopped range by 4, since they're all above 11 (the threshold above which Ode always adds 4 adventures). This makes the range 18-22.0. The average of this range is 20.0.

Finally, drinking with Frosty's Mug increases all values of the range by 30%, but they are floored. This can be seen in the table below. Frosty's Mug acts after everything else, so 18-22 are chosen to be modified.

The average must be calculated by finding the weighted average of each possible value that's produced from the range. The minimum of the range occurs with probability (1/num_values)*(1-chance of adding an adventure), where the chance of adding an adventure is the decimal portion of the max, in this case it is 0.0, since the max is 22.0. The maximum of the range occurs with probability (1/num_values)*(chance of adding an adventure). All other values in the range occur with probability 1/num_values.

• floor(18 * 1.3) = 23, occurs with probability (1/num_values)*(1-chance of adding an adventure) = 20% chance
• floor(19 * 1.3) = 24, occurs with probability (1/num_values) = 20% chance
• floor(20 * 1.3) = 26, occurs with probability (1/num_values) = 20% chance
• floor(21 * 1.3) = 27, occurs with probability (1/num_values) = 20% chance
• floor(22 * 1.3) = 28, occurs with probability (1/num_values)*(chance of adding an adventure) = 20% chance

The weighted average is the sum of each possible value multiplied by its probability of occurring. In this case, the range is 23-38, and the average is 25.6.

It should be noted that if the chance of adding an extra adventure is zero, then all values will occur with probability 1/num_values, where num_values = the number of observable values. If chance of adding an extra adventure is not zero, then num_values is equal to the number of observable values minus one, because the highest value is a special case of getting added when the game chooses the amount of adventures you get from the consumable.

For SHCs with no modifiers (14-18.0), this produces a value for num_values of 5; and for the above example from 24-31, this also produces a num_values of 5, since there are six possible values, but the highest value is a special case of being seen only after the game chooses the maximum value and adds one. Frosty's mug affects the drink's observable values in a predictable way, and that's why there are jumps in the observable values between 24 and 26.

Superhuman Cocktails

Modifiers	Possible Values					Average
Chance	20%	20%	20%	20%	20%
Base	14	15	16	17	18	16.00
+Ode	18	19	20	21	22	20.00
+Frosty	18	19	20	22	23	20.40
+Ode and Frosty	23	24	26	27	28	25.60

A Food Example

The math is the same idea for Food and Booze alike, here is an example of hi meins. Notice that, like with the Booze example above, there are jumps in the amount of adventures that are observable. So with a Fork, a player will never see an adventure gain of 31 or 35 for a hi mein.

Hi Meins

Modifiers	Possible Values									Average
Chance	6.25%	12.5%	12.5%	12.5%	12.5%	12.5%	12.5%	12.5%	6.25%
Base	21	22	23	24	25	26	27	28	29	25.00
+Munchies	22	23	24	25	26	27	28	29	30	26.00
+Milk	25	26	27	28	29	30	31	32	33	29.00
+Fork	28	29	30	32	33	34	36	37	38	33.00
+Munchies and Milk	26	27	28	29	30	31	32	33	34	30.00
+Milk and Fork	33	34	36	37	38	39	41	42	43	38.12
+Munchies, Milk, Fork	34	36	37	38	39	41	42	43	45	39.44

How to Spade

Many players will only try to find the observed range of a consumable with no modifiers. While this gives a good approximation of what the consumable will do, it does not tell the whole story, due to many consumables not having an integer maxadv value.

In order to properly spade a consumable, all observed values must be recorded, and the frequency of those values must be calculated.
