You expend this immurement and change the terrain in a close blast 4 until the end of the encounter. Replace the terrain in the blast with the following terrain and effects.
*: The area has natural illumination providing dim light.
*: The squares filled with bones on the ground level are difficult terrain.
*: The dragon skull platform is 2 squares higher than the ground (Athletics DC 26 to climb).
*: At the start of your turn, make an attack against each enemy on a bone square: +30 vs. AC; on a hit, the target takes 2d10 + 5 damage, and you slide the target 1 square (as bones shift and move it).
