Effect & research conditions
The technology costs 150 Food and 150 Coin and takes 10 seconds to research. The Zen Temple site is required. Its scope is Hand Infantry, not all infantry or every unit available from the same production building; check unit classifications before counting on the increase.
Research condition
Available from the Exploration Age. Research it at Trading Post or Tambo on a Zen Temple holy site.
When to research
Research when Hand Infantry will be a substantial part of the army and the force can engage targets without being screened out. The short research time makes it convenient before a planned fight, but its value falls if the opponent’s composition keeps those units from attacking. Compare the cost with training additional troops or investing in a broader improvement.
A broad class bonus with a map prerequisite
Master Lessons can benefit multiple Hand Infantry units, but only if they carry the relevant classification and can deal damage during the fight. Secure the Zen Temple settlement early enough that the Trading Post or Tambo remains available when research is needed. Use the technology before the army commits, then position Hand Infantry behind units able to absorb fire. The 10% increase does not remove their ordinary counters or change attacks from other unit classes.
