Editing Anima tree

Anima grass is created proportional to the pawn-hours spent meditating to it. Multiple pawns can meditate at the same time to speed up the spawning of the anima grass. At 100% effectiveness, one pawn-hour of meditation grows approximately 16% of one anima grass patch. After 12 pawn-hours of cumulative meditation time, grass growth slows by 50% to 8% of growth per pawn-hour. After 24 pawn-hours of meditation time, it slows to 25%, or 4% of growth per pawn-hour. Finally, it drops to 15% of the normal growth rate after 48 pawn-hours of meditation time. This counts all pawns that have meditated during a 24 hour period. This rate is also affected by the [[#Artificial buildings|artificial buildings]] surrounding the tree, up to a -30% of the growth. A full -30% penalty does not stop growth after 24 pawn-hours, suggesting that factor is applied multiplicatively. If there are multiple trees on a map, each will have its own anima grass and threshold, allowing more grass to be grown before hitting diminishing returns.

This ritual can grant a psylink to a pawn without one or improve the level of an existing psylink; even one granted using a [[psylink neuroformer]] or through an Empire [[Titles|bestowing ceremony]]. This only works on pawns with the Natural meditation type and a non-zero [[psychic sensitivity]].{{Check Tag|Verify}} [[Children]] {{BiotechIcon}} cannot link to the anima tree. Once the ritual is complete, 20 anima grass will die, and one new grass will sprout for every participant of the ritual. Any remaining or regrown grass can then be used for future linking rituals, however note that the grass has a limited lifespan of {{Q|Anima grass|Lifespan}} [[time|days]].

Psycasters regain psyfocus at a base rate of {{+|50%}} psyfocus per day spent meditating. Foci in range of the psycaster's [[meditation spot]] and of a focus type they share increase this rate additively. Anima trees have a base meditation focus strength of {{+|28%}} psyfocus per day. Each [[animus stone]] within 9.9 tiles increases the meditation effectiveness by {{+|2%}}, while each [[small nature shrine|small]] or [[large nature shrine]] within 9.9 tiles increases it by {{+|1%}}. Up to four buildings can affect the tree, for a maximum bonus of {{+|8%}} from 4 animus stones. This rate is also affected by the [[#Artificial buildings|artificial buildings]] surrounding the tree.

 

The maximum meditation focus strength is thus {{+|42%}} for an anima tree with no artificial buildings within 34.9 tiles and surrounded by five animus stones.

Building an artificial building within the 34.9 tile build radius will reduce the meditation strength and anima grass growth rate. The reduction is set by the following curve:

 

{| {{STDT| c_07 text-center}}

|-

|  0 || '''0%'''

}}

|  5 || {{--| 8%}}

| 10 || {{--|15%}}

| 50 || {{--|30%}}

 

Keep in mind that a pawn will preferentially meditate at the highest rate natural building, so two animus stones next to an anima tree will give +4% (+28%-28%+2%+2%) but two animus stones on their own will only give +2% (+34%-34%+2%). Without the artificial building penalty, both situations would be equivalent +36% (+34%+2%) as a pawn would always meditate at the animus stone and the anima tree would be ignored, though grass still grows.

[[Ruins]] also do not have any penalty '''so long as the ruins remain unclaimed;''' claiming the ruins will cause them to apply the usual penalty. Despite their similarity to other exempted objects, [[monument marker]]s {{RoyaltyIcon}} are considered artificial.

* The smaller (9.9 tiles radius), green circle is the range at which animus stones and nature shrines can link to the tree.

* The larger (34.9 tiles radius), red circle indicates where artificial structures will disrupt the tree. The "Build radius warning" option, turned on by default, will create a red line whenever you try and place a building.

* Option 1: Leaving the anima tree clear from artificial structures. You can still install attractive [[floor]]s and plant flowers (where grass won't spawn) to keep the area [[beauty|beautiful]] and meditators happy without affecting the tree. A bed and dining room just outside of the radius can help lower travel time. This method is ideal if you dedicate a colonist's entire workday to meditation. Psycasters can gain psyfocus at the maximum rate of 92% per day, or 3.83% per hour.  

* Option 2: Ignoring the artificial penalty entirely. Create your entire base right next to the anima tree, and surround the tree with [[wall]]s. This makes the travel time much shorter, and keeps your pawns safer against raids during meditation. In [[biome]]s where the [[Events#Beavers!|Beavers!]] event can happen (arid shrubland, tundra), it also keeps the ''tree'' safe.  

** While building close to the tree impacts the rate at which you gain psyfocus, the psyfocus gain provided by the tree is an "offset" on top of a pawn's base psyfocus gain of 50%/day. With 50 buildable items in the vicinity, the anima tree will not provide any bonus to meditation but any items providing bonuses will still provide the benefit. The lowest possible psyfocus gain is 50% per day while the maximum amount lost is -34% per day, if a single animus stone is used. A pawn will actually meditate at the animus stone over the anima tree but anima trees do not provide a bonus to animus stones, 2 animus stones are needed to see any bonus beyond 50% psyfocus gain per day. This will generate psyfocus at a rate of 2.08% per hour. With 5 animus stones, the rate will be 58% per day, or 2.42% per hour.
