Inferno cannon

The Inferno Cannon is a medium range siege weapon armed to centipedes only and it won't drop upon its death. It fires a projectile that sets anything within a 2.4-tile radius on fire, accuracy for touch range is 79, short is 42, medium is 18, and long is 6. While its shots deal trivial damage, the primary threat is that it starts fires that can consume large areas and cause extensive damage if left uncontrolled. Characters caught by its fire will run out of their cover in an attempt to put out themselves, and will not fight back when damaged, making them sitting ducks. Burns do not cause bleeding but extensive pain, which leads to shock and incapacitation, or uncommonly scar badly. Downed colonists are also liable to death by fire unless rescued or put out. Shots can burn flammables through walls, so use extreme caution when opening ancient shrines as you may not want to trigger the spacers while threat still lingers around.

Defense

If you haven't already switched from wood walls and floors, Inferno Cannons are a major threat. To avoid the worst of the collateral fire damage, build bunkers made of stone to fight Centipedes from, and keep firefoam poppers handy just in case fire threatens your stockpiles or farm fields.

Devilstrand clothing, especially dusters, offers a lot of protection against fire damage. Consider investing in some if you can.
