Bridge of Graves

You summon a bridge formed from grave dirt and tombstones that allow thralls to move with great speed. The 10-foot-wide span must start at the ground on a point within range, and it extends as a horizontal plane, either in a straight line or at any angle up to 45 degrees upward or downward, for up to 120 feet. This bridge has AC 10, Hardness 30, and 40 Hit Points. A thrall on or adjacent to the bridge can move to any location on the bridge when you command it to Stride. You can Dismiss the spell.
