Attempted to verify the claim "This only works on pawns with the Natural meditation type and a non-zero psychic sensitivity.[Verify] Children cannot link to the anima tree."

• Pawns without the Natural meditation focus type cannot even participate in the Anima Tree Linking ritual. By default, they are in the greyed-out "Not participating" row in the ritual UI. Attempting to drag them into the Participants row will not work, and the game tells you "Must have natural focus type". Attempting to put them in the Linker role will not work, and the game tells you "Must be a colonist with the natural meditation focus type who is below maximum psylink level."
• Attempting to put a pawn with 0% psychic sensitivity in the Linker role does not work, and the game tells you "Must not be psychically deaf."
• Children with the Natural meditation focus type can participate in the ritual. However, attempting to put them in the Linker role will not work, and the game tells you "Only adults can link with an anima tree".

Also missing in the Anima Tree page was information on how much grass is retained after a linking ritual. The amount of grass restored is dependent on the quality of the ritual, according to a SimpleCurve hardcoded into the RitualOutcomeEffectWorker_AnimaTreeLinking as follows (x = quality, y = grass restored):

• (0.2, 0)
• (0.4, 1)
• (0.6, 3)
• (0.8, 5)
• (1, 8)

Quality is determined by participant count, which can be seen changing as you alter the number of participants in the ritual UI. The SimpleCurve is in the XML for the 'AnimaTreeLinking' RitualOutcomeEffectDef (x = participants, y = quality):

• (1, 0.2)
• (2, 0.4)
• (4, 0.6)
• (6, 0.8)
• (8, 1)

Presumably this convoluted setup where you have to evaluate through two different SimpleCurves owes to technical limitations on the possible range of ritual qualities.

You can check all of this by making a testing scenario with at least eight tribals and an anima tree with 20 grass (to make grass on demand, select the anima tree, turn on dev mode, turn on god mode, and press the "DEV: Add 100% progress" button over and over again until you have >=20 grass). The ritual UI itself has a line at the bottom of the ritual description, which reads "With _ additional participants, _ anima grass will be restored at the end of the ceremony." The outcomes read as follows:

• 7+ additional participants: 8 grass restored
• 6: 6
• 5: 5
• 4: 4
• 3: 3
• 1-2: 1
• 0: 0

EDIT: paragraph breaks

Also satisfied a stub request to fill out details about meditation at an anima tree works. I'll be putting citations for each of the claims below - if the citation does not end in '.xml', it can be found in RimWorld's C# assembly.

- Meditation is a form of solitary recreation (Jobs_Joy.xml). It has no specified joyGainRate, and so defaults to 1 (JobDef.joyGainRate).

- Every tick of meditation, joy is given to the pawn through the function JoyUtility.JoyTickCheckEnd, with the argument "extraJoyGainFactor" set to 1 (JobDriver_Meditate.MeditationTick).

- JoyTickCheckEnd provisionally grants a joy = extraJoyGainFactor * curJob.def.joyGainRate * 0.36 / 2500, which in this case is therefore 1*1*0.36/2500 = 0.000144 = 0.0144% (JoyUtility.JoyTickCheckEnd).

- This provisional amount is multiplied by the pawn's tolerance for solitary recreation, and then given to the pawn (Need_Joy.GainJoy).

Absolutely top tier work. Thank you so much!
