Kumis
Kumis is an Exploration Age technology researched at a Trading Post or Tambo built on a Tengri Shrine holy site. It supplies a Yak carrying additional Food every three minutes of game time, up to 30 minutes, so its value depends on researching early and having time to collect the later deliveries.

Effect & research conditions
Research costs 150 Wood and 150 Coin and takes 10 seconds. The effect delivers one Yak with an additional 150 Food for every three minutes of game time, up to the 30-minute cap: at most ten deliveries and 1,500 bonus Food. The schedule is timed rather than an immediate resource grant, and each Yak must still be collected and used.
Research condition
Exploration Age; Trading Post or Tambo on a Tengri Shrine holy site. Cost: 150 Wood and 150 Coin. Research time: 10 seconds.
When to research
Research early if the holy-site location is available and the match is likely to last long enough for multiple installments. The full 1,500 Food is a maximum over time; later research leaves fewer delivery intervals. Keep workers and army safe while gathering from or protecting the delivered Yaks.
Calculate the maximum timed Food bonus
Kumis delivers one Yak carrying an additional 150 Food for every three minutes of game time, up to the 30-minute cap. That allows at most ten timed deliveries and 1,500 bonus Food if researched early enough for every interval. The bonus is additional Food carried by the Yak; the technology does not immediately add the full maximum to the player's stockpile. The Yak itself must still be collected and used, so protect the delivery route and leave room to manage it.
Holy-site access and research timing
The Exploration Age research costs 150 Wood and 150 Coin, takes ten seconds and requires a Trading Post or Tambo built on a Tengri Shrine holy site. Researching later means fewer three-minute intervals remain before the cap. Confirm that the site is accessible and that the match is likely to last long enough for the deliveries to justify the investment. If the player needs immediate Food for a defense, an arriving Yak later may not solve the current shortage.
