Corrosive Gas Generation

You release a burst of corrosive gas around yourself.

Releases gas for (level based) rounds
Cooldown: 40 rounds

Corrosive Gas Generation is a physical mutation generates corrosive gas. For each round that this mutation is active, the user releases a total density of 800 units of corrosive gas, spread evenly into the tiles surrounding the user. Generally this results in 100 density units of gas in each tile (in the 8 surrounding tiles), unless the user is at the edge or corner of a zone, in which case the gas release density will be slightly higher due to the reduced number of surrounding cells.

Creatures with this mutation are immune to all sources of corrosive gas. They are not immune to acid or poison gas.

Released gas inherits the phase of its owner.

Gas damage is highly variable due to the way that gas spreads and dissipates, but the damage caused by high-level Corrosive Gas Generation, with all gas being released from the same cell, can deal upwards of 50 damage per round.

Advantages & Disadvantages

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


  • Deals extremely high damage to walls and doors, even at low levels (this includes force walls)
  • Can be used to break through walls and explore areas more easily, similar to Burrowing Claws
  • Does not damage "loot" items, such as weapons, armor, or artifacts
  • At high mutation levels, can also deal significant damage per turn to creatures
  • Synergizes well with other gas-generating mutations and abilities, such as Sleep Gas Generation
  • Most enemies will usually avoid entering corrosive gas cloud, making this mutation a powerful zoning tool, especially in early game


  • Can damage friendly creatures, turning them hostile toward you
  • The spread of gas cannot be easily controlled, so it's hard to target specific enemies or walls without affecting other things nearby
  • Desecrates shrines that it comes into contact with
