Earthen Ramparts
Exploration 6
At your command, walls of earth rise around your position and offer protection.
Earthen Ramparts is a 6th-level ritual.[Dr366:28]
You channel the earth around you into defensive mounds. Earth rises to create a wall 2 within 10 squares of you. The wall is 2 squares high. On one side of the wall (your choice), the earthen mound is sloped so creatures can climb atop the wall. Climbing atop the mound from that side costs an extra square of movement. For every 10 points you have on an Arcana or Nature check result, you can create another wall 2 within 10 squares.
