{the ceiling cracks, inflicting \rollConv\ Damage on a single target below}% Description
{
The caster focusses on a stone ceiling, and demands that it crack and splint in a precise pattern, to send a hunk of rock onto someone's head.
If the target fails to notice the hunk of rock, they receive \rollConv\ Damage.
The ceiling generally remains intact, despite the small missing chunk, although repeated castings will inevitably bring down an entire floor of a castle, and \emph{might} cause a cave-in when underground.
The spell can target ice as easily as any other type of solid material, but cannot target wood.
Dense rock may give a penalty to the spell's \gls{tn}, at the \gls{gm}'s discretion.
A failed roll generally indicates that the crack formed too slowly, and made too much noise, signaling to anyone below that rock might fall at any moment.
Rolls with a high failure-margin might indicate that the rock failed to move entirely, and that anyone below the ceiling clearly understood that nothing could move or break it.
