You reshape
matter within short range in an area no larger
than a 5-foot (1.5 m) cube. If you use only one
action on this ability, the changes you make are
crude at best. If you spend at least ten minutes
and succeed at a hindered appropriate crafting
task, you can make complex changes to the
material. You can’t change the nature of the
material, only its shape. Thus, you can make a
hole in a wall or floor, or you can seal one up.
You can fashion a rudimentary sword from a
large piece of iron. You can break or repair a
chain. With multiple uses of this ability, you
could bring about large changes, making a
bridge, a wall, or a similar structure.
