Editing Ancient shrine

[[File:Ancient_danger.PNG|400px|right|thumb|Ancient shrine pre-1.1]]

'''Ancient shrines''', commonly referred to as '''ancient dangers''' due to the event card, are large structures that spawn on the map upon generation. They take the form of a massive, unexplored room.
though they may be damaged somehow after map generation. If they spawn damaged, they are most likely [[ruins]].

Having a colonist walk by the walls of the structure will trigger an [[Events#Ancient Danger|Ancient danger event]] prompting:

 ''"As (Colonist Name) draws near the ancient wall a sense of foreboding overcomes him. (S)He isn't sure why, but (s)he feels this dusty structure may contain great dangers"''

== Description ==
Ancient shrines are large rooms of stone or steel walls. In contrast to [[ruin]]s, the walls of the shrine always begin undamaged and in perfect condition. Ancient shrines generate either partially or completely under natural [[rock]] formations.  Ancient shrines are not guaranteed to spawn on small or medium maps, but will always spawn on larger map sizes. Two or more may spawn of one of the largest map sizes.

There are two components to the shrine's "danger":
* A non-human threat immediately revealed when opening the shrine. This can be either [[mechanoid]]s, [[insectoid]]s with their requisite bug [[hive]]s, or even a few [[fleshbeast]]s if the [[Anomaly]] DLC is installed. Beware - even [[centipede]]s can appear in an ancient shrine.
* The beings inside the [[ancient cryptosleep casket]]s. They are not always hostile. This can contain a human, a human and a [[megascarab]], a group of megascarabs, or nothing. Humans will belong to one of two [[Ancient]]s factions; one faction is hostile, the other faction starts off neutral. Megascarabs are always non-hostile. Opening 1 ancient cryptosleep casket will open all the caskets. Humans may spawn [[downed]] or as [[corpse]]s.

Due to being fully enclosed, one cannot see within the shrine, and hovering over the grayed out area as seen in the picture will only say 'Undiscovered' in the bottom left corner.  The only way to find out what is inside is to deconstruct or destroy a wall section. 

There are many rewards within the ancient shrine. It can contain [[artifact]]s such as [[psychic animal pulser]]s or [[psychic insanity lance]]s, and valuable items like [[luciferium]] are common. Ancients often carry [[plasteel]], [[gold]], and [[advanced component]]s; even their [[corpse]]s carry loot. Ancients can spawn with [[synthread]] and [[hyperweave]] clothing, [[power armor]], high quality weaponry, or may be naked.

In addition to the loot, ancient shrines will contain ancient cryptosleep caskets, [[table]]s of different sizes, [[column]]s, and/or [[urn]]s. Their floors are generally made out of [[flagstone]], [[steel tile]], or [[stone tile]]. These can all be deconstructed.

== Analysis ==
===Dealing with the danger===
[[File:Ancient danger traps.png|thumb|400px|right|A [[spike trap]] tunnel, likely able to kill anything short of [[centipede]]s.<br>Build the traps first, then the walls.]]
When opening the ancient shrine, it is recommended to not deconstruct the wall, but to destroy it with ranged weaponry. This gives you some distance to deal with [[scyther]]s and other threats. Make sure to keep colonists [[draft]]ed, or toggle their [[threat response]] from Attack to Flee.

The [[spike trap]] tunnel on the right is likely to take out [[scyther]]s, [[lancer]]s, and [[megaspider]]s that inhabit the shrine. For [[centipede]]s, it is recommended to have a [[bolt-action rifle]] or [[sniper rifle]] on hand and [[kiting|kite]] the centipedes. 

If a trade [[caravan]] happens to spawn near the ancient danger, you can open it. Caravans likely have enough firepower to clear the entire danger, or at least, severely weaken it. In a similar fashion, shooting an ancient cryptosleep casket will unleash its ancients - mechs, insects, and ancients should all fight each other.

===Dealing with ancients===
[[File:Ancient danger prisoner.png|thumb|300px|right|"Ancient soldiers" have shockingly little resistance, so long as they are captured (and not rescued first).]]

The shrine itself contains a lot of loot, but so does its ancients. Even if the ancients are neutral, it is worthwhile to [[arrest|capture]] or kill them for assault weaponry, armor, and materials. If a stray bullet doesn't hit the cryptosleep caskets, they should remain closed, even after renovating the rest of the danger. 

If captured, ancient soldiers have incredibly low resistance, making them very quick recruits.

*'''Using fire'''
The ideal method to capture ancients is not through a gunfight. Not only is it dangerous, but combat comes with an automatic [[AI Storytellers#Enemy death on downed|death on downed]] chance. 

Instead, a better way is through [[fire]]. First, enclose the shrine with a [[door]], so that it is "Inside" for [[temperature]] purposes. Place some fuel and raise the temperature up high. Contiously throw [[molotov cocktail]]s or other flame weapons until the room hits at least {{Temperature|200}}. Then shoot the cryptosleep caskets. Both hostile and friendly units will be downed through [[heatstroke]], avoiding the usual death on down chance. 

Once heatstroke severity reaches around 70%, or if there were no conscious pawns in the first place, deconstruct the walls so that the room is considered "Outside". This stops heatstroke and helps slow fire spread. You can then strip and capture the ancients as you please. [[Firefoam pop pack]]s, if available, are recommended to make saving things easier.

The ancient cryptosleep caskets will be at risk of destruction, which can kill ancients and damage gear. But they have quite a bit of health, so you can extinguish important items and capture important pawns before that happens.

== Loot table ==
{{Rewrite|reason= Percentages based on a random sample - multiple runs of each same need to be done to verify their accuracy. Dev Mode ->  Open Debug Logging Menu -> Thing Set Maker Sampled -> MapGen_AncientTempleContents}}
The following loot can be found scattered on the floor of an ancient shrine. The percentage relates to the chance that the loot in question will occur in a given ancient shrine. For stackable items, it is currently unclear how the size of the stack to be spawned is generated.{{Check Tag|Detail Needed}}

=== Ruined objects and crates ===
{{Ideology|no category}}
Ruined objects and crates like [[hermetic crate]]s and [[security crate]]s may spawn inside the ancient shrine. While the ruined objects will yield nothing upon destruction whether through combat or deconstruction, the crates will yield loot when opened, ranging from [[hyperweave]] to rarely [[thrumbo horn]], and also includes some [[Royalty DLC]] items such as [[techprint]]s, if the DLC is also enabled. The crates yield nothing when demolished as well.

== Version history ==
* [[Version/0.8.657|0.8.657]] - Added
* [[Version/0.12.906|0.12.906]] - [[Artifact]]s now found inside.
* 1.1 - generation was reworked to improve their structural style. Prior to that, they were merely a room built out of stone.
* [[Version/1.3.3066|1.3.3066]] - Ancient dangers will no longer be generated with hostile mechs in peaceful mode.
