Oni Masks - a tech researched at the shinto temple which allows a shinto priest to consecrate a mask for the samurai. They increase hitpoints.

Way of the kitsune - a tech researched at the shinto temple which allows shinobi to have reduced time on their disguises!

Embodiment of the Tengu - A tech researched at the shinto temple which increases samurai move speed!

Resistance of the Tanuki - A tech that allows town centers to spawn a pack of wild dogs that attack any units (friend or foe) that are not garrisoned in a building.
