The incendiary shell is a type of mortar shell that explodes into a conflagration, dealing flame damage and setting the area alight.

Acquisition

Incendiary shells are made using 10 steel and 20 chemfuel at a machining table and requires Mortars to be researched. Requires a Crafting skill of at least 4. The steel cost is increased to 20 if the Classic Mortars difficulty option is enabled.

They can also be purchased from traders.

Summary

When fired from a mortar, incendiary shells deal 10 Flame damage in a 2.9 tile radius. They also set the area on fire and creating chemfuel puddles which themselves burn.

When damaged beyond 70% of its health, it will explode after between 30 ticks (0.5 secs) and 60 ticks (1 sec), dealing 10 Flame damage in a radius around itself. The radius depends on the quantity in the stack, with a single shell covering a 2.9 tile radius, and expanding this radius proportional to the square root of the stack size times 0.4 up to a maximum radius of 6 tiles at a full stack of 25.

They are also used in the construction of IED incendiary traps.

Analysis

Offensively, incendiary shells should be used whenever there's something to set on fire. A siege next to a bunch of trees, or an enemy base with power conduits in the open. Note that the game will automatically cause rain if fires get too out of control.

Sieges can and will use incendiary shells against you, which will ravage through rooms floored with carpet, hay, or with otherwise flammable items. Firefoam poppers are very strong at protecting against fire.

Storage

As with all explosive items, these should be stored in separate storage containers. For maximum protection, put each stack of shells in a separate 1x1 stone box to prevent chain reactions. Pawns currently in a tantrum should be stopped at all costs, whether it be by arresting, creating another stockpile zone with a higher priority than the shell zone and prioritizing hauling the shells, or simply by shooting the pawn.
