Archery is a Tier Two technology that can be researched after Hunting.

Once researched, it grants a defensive bonus of 250% (increase of 150%) to troops on forest tiles. If you have a defence bonus, a shield will appear around the health.

It also unlocks Archers, which are cheap ranged units for the early game.

Archery leads to Spiritualism.

The Hoodrick tribe starts with this technology.
