You can start knowing this ritual if your first god was Nyalda and, when the First Clan split, your ancestors were the most dissatisfied.

Otherwise, you naturally learn it through sacrifice to Inilla.

• Improved foraging.
  More food is always a good thing in this game. Note that your foragers bring in food throughout the year, not just when you send out a mission or conduct a venture.
  
  
• A magical vessel of your choice.
  Your choice from several treasures grouped by being baskets/bowls/drinking horns, rather than by what they actually do. Only available if you successfully win the gods' trust by presenting them with food in the first stage of the ritual.
  
  
• Strengthening of the quester’s abilities.
  Increases Food and Lore by a full level each (that is, the component skills of Foraging).
  
  
• Strengthen all your priestesses and female leaders.
  Aids female leaders in tests vs. Divine for several years.
  Requires succeeding at descending into a cave with Nyalda in the first stage of the ritual.
  
  
• Make your foragers into keen-eyed scouts.
  Significantly increases your chance of spotting raids on your lands; doing so means you face full raids with a larger force and have a chance to fight off herd raids rather than just losing the cows. If you're getting a lot of messages that you completely missed herd raids, this might be a good thing to look into!
  
  
• A treasure, the Basket of Inilla.
  "Grants divine blessing to worshippers of Inilla"—that is, bonuses on particular skills.

Many Sacred Time magic allocations are helpful for this ritual. However, they are not all equally useful.

Wilds magic (granted by circle members who worship Inilla herself and her husband Dostal) is extremely useful, as is Exploring (Zarlen).

Ritual (Shaman, Relandar, seven different religions on the circle) and Harmony (Hyalor) can also be useful in more than one situation.

And Diplomacy (Ekarna, Hyalor), Fields (Nyalda) and Pastures (Busenari, Gamari, Uryarda) are each useful for a single choice.

As always, you must put at least two points of magic into any area to have an effect during rituals.

As with all other rituals, there's a penalty for repeating this one too soon! And unlike, say, Busenari Light Finder, there's no reason to do that. Wait the full five years.

You can ask Rider clans to help, and should. Clans that side with you over Cenala will almost certainly help, unless you've earned a reputation as a rite-shirker by refusing to grant them equivalent help in scenes. If Cenala isn't a factor, having a good diplomat on the circle helps, as does having

You can also ask Wheels to help. Though Inilla is the least-regarded figure of their pantheon (and I think it's correspondingly hard to convince them) it is possible.

Technically, I don't think you actually have to make an unusually large sacrifice here.

In practice, I pretty much always max out the goods slider myself. Just in case.

The quester for this ritual must be a non-shaman woman, and the game recommends one skilled in Food and Lore. Alas, high Food and high Lore are rarely found in a single person, let alone an Inilla worshipper. So you're going to have to make compromises.

High Food alone may get a quester through the first three stages of the ritual; high Lore might work, though it's less likely to have a suitable loremistress on hand.

Magic can be useful for some choices, though it definitely won't get the quester through on its own; the same is true of Diplomacy.

It's also worth noting that all choices in the last stage of the ritual test Bargaining.

As usual, Inilla worshippers do have an advantage—not a huge one, but if your Inilla and Busenari priestesses are tied for best Food in the clan, pick the Inillan.

Though Inilla is the daughter of the Fire Tribe's leaders, they don't actually know her. (In the Golden City the Riders had no use for a goddess of foraging; therefore, Inilla was only born after they left.) Before she can help them, she has to convince them that she's their daughter—a member of the family and tribe, someone they can trust and rely on.
