Gray bands extend from your fingertips,
wrapping themselves around the wall like
a brace, strengthening it for the coming
assault.

You reinforce a rock formation or stone
structure. The earthfast spell doubles
the structure’s hit points and increases
its hardness to 10. This spell does not
function on constructs.
