This rune serves to still the movements of the earth within it's radius, reducing the impact of quakes and preventing cave-ins.. All stone structures which are reasonably well constructed will not fall unless acted upon by a sentient being. The area affected by the rune is dictated by the skill of its construction. With enough such runes, even massive underground cities can be built. Go to Comment
tuck a small mammel into this 2' box,carry it under your left arm and the little creature takes some damage for ya and some spells cast on you are misdirected to it. If you do't mind the muffled screams!
