Excavation
Exploration 6
Earth and loose stone disappear bit by bit before your eyes, leaving a rough trench in its wake.
Excavation is a 6th-level ritual.[Dr366:29]
You clear 1 square of earth and loose stone within 5 squares of you, leaving the start of a trench or a tunnel. For every 10 points on the Arcana check result, you clear another square. The material disappears over the course of the ritual’s duration and is scattered across the world.
