Bamboo Field

A type of Terrain.
From the Book of Engoku:

Description

Bamboo typically isn’t very wide, but when it grows densely it may as well be redwood. Bamboo Fields are marked by bamboo shafts staked around the area. Bamboo Fields have several effects. Projectile and Thrown Weapons (excluding White weapons) may not be used at a range greater than 20 feet. Likewise, you may not fire a bow or throw a weapon (again, excluding White weapons) into a Bamboo Field.
Line of Sight is limited to 20 feet. One or more noncombat Reeves wander the area armed with unlimited Lost. The Bamboo Fields tend to focus on individuals who are alone, running, fighting, or using an Ability.
