You release a burst of sleep gas around yourself.

Releases gas for (1 + Level / 2) rounds

Note that for easier wiki use, ID has its GasObject constructor appended to it. The ingame id is GasGeneration with constructor="SleepGas".

Sleep Gas Generation is a physical mutation that both player characters and non-player characters can use to generate gas that induces asleep in the surrounding squares. A secondary effect of having this mutation is that the creature will also become immune to all sleep gas, including those generated by other hostile creatures.

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 the surrounding 8 squares of 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}. If the creature fails this save, they will fall asleep for 4d64-24 (Avg: 14) + Mutation Level.[1]

Advancement Table[edit | edit source]

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.

Mutation Level Rounds Toughness Difficulty Save Turns Asleep
1 1 16-86 (Base: 6) 4d6+15-25 (Avg: 15)
2 1 17-87 (Base: 7) 4d6+26-26 (Avg: 16)

10 5 25-95 (Base: 15) 4d6+1014-34 (Avg: 24)

Advantages & Disadvantages[edit | edit source]

Advantages[edit | edit source]

  • Can serve a defensive purpose as fairly powerful panic button.
  • 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[edit | edit source]

  • 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.
