|This ritual causes an area of dirt or stone to become impervious to digging. The affected area becomes immune to damage caused by mundane means. Magical attacks may be able to penetrate the enchanted earth, but the material is considered to have resist 20 all. This ritual also prevents creatures with a burrow speed from moving through the affected earth.|
|This ritual may be extended for another day, if any arcane caster expends a healing surge while touching the affected area and succeeds on a DC 20 Arcana check. If the ritual is extended for a year and day in this manner, it becomes permanent.|
|Optional: This ritual may also be inscribed on between 3 and 8 rods made of a rare earth type, worth at least 1000 gp each. When the rods are placed in the ground and the ritual is activated, all the earth and stone within the perimeter defined by the rods are affected as above, up to a depth of 100 ft. When used in this manner, the ritual lasts for one hour and cannot be renewed. The component cost for this ritual when casted in this manner is 250 gold per focus used, plus the foci themselves.|
