The '''high-explosive shell''' is the most common kind of [[mortar shell]], that deals 50 damage in a 3-tile radius upon exploding.

== Acquisition ==
High-explosive shells are made using 15 [[steel]] and 15 [[chemfuel]] at a [[machining table]] and requires [[Research#Mortars|Mortars]] to be researched. Requires a [[Skills#Crafting|Crafting skill]] of at least 4. The steel cost is increased to 25 if the [[AI_Storytellers#Player_tools|Classic Mortars]] difficulty option is enabled.

They can also be purchased from [[traders]].

Finally, [[siege]] raids will have high-explosive shells drop podded to them, and if unused by the raid, can be taken by the player.

== Summary ==
When fired from a mortar, {{lc:{{P|Name}}}}s deal {{P|Damage Base}} [[Damage types#{{P|Damage Type}}|{{P|Damage Type}}]] damage in a {{P|Blast Radius}} tile radius.

When damaged beyond 70% of its health, it will explode after between {{ticks|30}} and {{ticks|60}}, dealing 50 [[Damage Type#Bomb|Bomb]] 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 {{#expr: 2.9+((24*0.4)^0.5) round 2}} tiles at a full stack of 25.

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

== Analysis ==
It is the standard shell for mortars, dealing high damage and having a decent blast radius. Given the mortar's inaccuracy, it's best to have a battery of mortars firing at once to deal heavy damage to the enemy.

It is quite resource-intensive, so it's best to wait until mid-game until beginning the use of mortars.

They are effective against most enemies; [[Raid#Siege|siege]] bases, resting or charging raiders, crashed ship parts and their mechanoid guards. While two mortars are enough against siege bases, around 4 - 8 will be needed for direct attacks on raiders.

They are less effective against enemies equipped with [[shield belt]]s, as the explosion is blocked by the shield. A high quality shield belt can survive a blast and regenerate faster than the mortar fires. Pairing these with other mortars firing EMP rounds can overcome this problem easily.

=== 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.

== Version history ==
* [[Version/0.18.1722|0.18.1722]] - Added to replace mortar type system.
* 1.1 - Crafting cost was increased (20 --> 25 steel, 10 --> 15 chemfuel).
