Spelljammer
Environmental Movement
Environmental Movement is an advanced martial artist ability.

Prerequisites: WP 19, DEX 22, Martial Artist 6

This ability is similar to the skill Woodland Movement except that it is not limited to wooded areas but can include any locations where the GM has restricted movement due to impediments hampering movement. This could crowded market, a boulder strewn field, or anything else that reduces movement.

In all other ways, it works in identical fashion to Woodland Movement (c.f.).
