Glotrot

is an illness that can be diagnosed from an initial stage of a, after a week or so will fully develop into , and the tongue will begin fully rotting away. It can be contracted by drinking, cooking with, or falling into. Many creatures that are made of or use as a form of attack can also make the player character contract a, such as ,  tripping the player character into a puddle of it, or  spewing the liquid.

Initial Stages
The initial stage of is set to 0.

Every day after the initial contraction (1,200 turns), a toughness save with difficulty 13 will be rolled, or a check to see if 1d20+Toughness Modifier > 13. If this is the case, the stage of decreases by one. A +3 bonus can be added to the save (making the save target effectively 10 instead) by either drinking or eating or cooking with a. These bonuses cannot stack.

If the total stage count is less than -1, the player has shaken off the onset and is fully cured. This message will appear in the message log:

Else, this cycle will continue until the stage is equal to or greater than 3, or a total of 5 or more days have passed, the  will progress into stage 2.

Glotrot Stage 2
Contracting has effects even before the tongue rots away: A new timer starts once stage 2 begins. Every day after entering the second stage of (1,200 turns) the stage will increase by one. Two days after entering this stage, you will get the message and have a bleeding of 1d1 damage with a toughness save of 25. Once the stage is equal to 3 or greater(after three days have passed), it proceeds to the full onset.
 * Drinking water has a 25% chance of causing the player to vomit, putrefying 4 drams (or as much as it can) of the liquid as well as making the player dessicated. To prevent contaminating a full waterskin, it is recommended to separate the water so each waterskin only has 4 or so drams inside.
 * Eating or drinking will cause bleeding of 1d1 damage with a toughness save of 25.

Full Onset
Fully rotting away a tongue has multiple consequences:
 * Ego and Snake Oiler no longer have any effects during trading, and a trading penalty will be applied.
 * All dialogue choices are replaced with "Nnnnnnnnnnnnnnn.", unless the player has Telepathy. This means that quests that require speaking to someone cannot be progressed.
 * Proselytize can not be used without a tongue.
 * Drinking water still has a 25% chance of causing the player to vomit, putrefying the liquid as well as making the player dessicated.

Curing Glotrot
The main way to cure is through drinking the Flaming Ick. The recipe is randomly generated each game and specified inside the. The Flaming Ick will always consist of 3 different liquids (1 dram, 1 dram, and 3 drams respectively) to be drunk out of a flaming. The exact proportions do not matter: only for the third liquid to be the primary liquid (be the largest component of the mixture). The container type also does not matter as long as it is able to become flaming without being destroyed. Flaming happens when items get hot such as by being left on a campfire.

The possible liquids are:
 * Asphalt (First and second liquids only)
 * Oil (First and second liquids only)
 * Blood (First and second liquids only)
 * Salt (First and second liquids only)
 * Honey
 * Wine
 * Cider
 * Sap
 * Water (third liquid only)

The Flaming Ick can be drunk even during the stage, where it will be fully cured before the tongue rots away. However, if this was not done in time, regrowing the tongue becomes an additional step needed to fully cure.

The first half of the cure has succeeded if the player receives this message:

However, is not fully cured. To get the cure message, the player must regenerate their tongue. This can be achieved in multiple ways:
 * The Regeneration mutation
 * Applying an
 * Sleeping in a
 * Using a

Once the tongue grows back, the player has successfully cured.

Regrowing a tongue without drinking the Flaming Ick will not cure, and the tongue will begin to bleed and rot away again.

Achievements

 * Losing one’s tongue as a result of will grant the Say No More Steam achievement.
 * Regrowing one’s tongue as the final step of curing will grant the Tongue in Cheek Steam achievement. Additionally, this will grant the Synolymb achievement if the player does not already have it.
