Sleep Gas Generation

You release a burst of sleep gas around yourself.

Releases gas for (level based) rounds
Cooldown: 35 rounds

Sleep Gas Generation is a physical mutation generates sleep gas, which can cause other creatures to fall asleep. Creatures that have this mutation are also themselves immune to all sleep gas, including sleep gas generated by other hostile creatures. This immunity does not extend beyond gas (it won't prevent other forms of sleep).

In order to be affected by sleep gas, a creature must respire. Robots and holograms do not respire and cannot be affected by sleep gas.

Generating gas must be toggled on in the abilities menu. Upon choosing to generate gas, at the end of each turn, sleep gas will generate in all of the open-air tiles surrounding the generator, excluding cells with occluding objects such as walls or closed doors. Once toggled on, the ability cannot be turned off until it has finished generating gas for the full number of turns based on the current mutation's level. The density of the gas in each cell is ${\frac {800}{\text{total cells}}}$. By default, this would mean a minimum density of 100 sleep gas for each of the surrounding 8 squares. Occluding squares will cause the remaining empty cells to have higher concentrated density of sleep gas, with a maximum density of 800 if only one cell is non occluding.

Any creature that is not immune to the effects of sleep gas that enters these gas clouds must make a Toughness save of $5+{\text{Mutation Level}}+{\frac {\text{Density}}{10}}$. Items such as the vinewood sap mask or gas mask provide a bonus to this Toughness save and reduce the effective density of gas for purposes of the calculation. If the creature fails this save, they will fall asleep for 4d64-24 (Avg: 14) + Mutation Level rounds.

Advancement Table

Due to the difference in save depending on the gas density, three values will be given: the minimum and maximum values assuming that all 8 surrounding cells are non occluding or all but 1 cell is non occluding respectively, and a base value before the density is calculated. This also assumes that the gas in one cell was generated for only one turn. If gas is generated for multiple turns, the density can increase to significantly higher levels.

Advantages & Disadvantages

This section is opinion-based. Your mileage may vary.

Advantages

• Can serve a defensive purpose as fairly powerful panic button.
• Is quite powerful throughout the entire game, even if left at level 1.
• Can serve an offensive purpose, as sleeping enemies suffer a large DV penalty and attacks against sleeping enemies get a bonus to penetration.
• Grants immunity to sleep gas.
  • This does not make the player immune to falling asleep, just to the effects of sleep gas.
• With high enough Willpower and a high enough mutation level, the player can produce sleep gas constantly or near-constantly.

Disadvantages

• Enemies who do well enough on their Toughness save may resist the effects of the sleep gas.
• Ineffective against ranged enemies, as the difficulty of the Toughness save generally drops off further away from the source of the sleep gas due to lower gas density.
