Antigrain warheads cannot be crafted nor bought from [[trader]]s. Instead they can only be acquired as a reward for performing [[quests]]. Note that quest rewards are selected with a weighted random generator, so there is no way to guarantee access to antigrain warheads in a given play-through. Anecdotally, it is often reported that the increased number of reward options added by the [[DLC]] dilute the reward pool with more options.

 

They can also rarely be found inside an [[ancient shrine]].

When fired from a mortar, {{lc:{{P|Name}}}}s deal [[Damage types#{{P|Damage Type}}|{{P|Damage Type}}]] damage in a {{P|Blast Radius}} tile radius, dealing {{P|Damage Base}} at the center and {{#expr: {{P|Damage Base}}*0.2}} damage at the extreme edge of the radius and linearly interpolated in between. It will also set fire to roughly 22% of the affected tiles.

When damaged beyond 70% of its health, it will explode after between {{ticks|30}} and {{ticks|60}}, dealing [[Damage Type#BombSuper|BombSuper]] damage in a radius around itself. The radius depends on the quantity in the stack, with a single shell covering a 14.9 tile radius, and expanding this radius proportional to the square root of the stack size times 0.4 up to a maximum radius of {{#expr: 14.9+((24*0.4)^0.5) round 2}} tiles at a full stack of 25. As above, it will deal {{P|Damage Base}} at the center of the explosion, {{#expr: {{P|Damage Base}}*0.2}} damage at the extreme edge of the radius and be linearly interpolated in between. It will also set fire to roughly 22% of the affected tiles.

Deterioration damage, however, will not cause an explosion, and the warhead will "deteriorate to nothing" instead.

 

They are also used in the construction of [[IED antigrain warhead trap]]s.

As with all mortar shells, it is heavily advised that you keep it in a safe place where it cannot deteriorate, come under fire, or be targeted by a [[Mental break|tantrum]]. In addition to the loss of the antigrain warhead itself, its detonation is likely to cause massive damage to your base, anything inside it, and its occupants. If a tantruming pawn does decide to punch an antigrain warhead, try arresting them. If your pawns are too far, shooting them may be the better option than the alternative - the injuries, mood and social penalties, and even risk of death are still better than the almost-guaranteed death of the tantruming pawn, let alone the collateral damage. For maximum safety, consider sealing it behind a quickly-deconstructable wall, ideally under thick mountain roof on the small chance that a mortar hits that single tile.
