Francisca (3.5e Equipment)
From D&D Wiki
A francisca is much like an ornate throwing axe. However, they have a tenancy to bounce when they don't hit anything soft (such as an opponent). When a francisca misses, it has a chance to hit anything in 15 feet of the target. Roll 1d12 to determine the direction it goes in. If anything is in it's path, the francisca makes an attack modified with the thrower's BAB with a -8 penalty. If an enemy is in the square that the francisca is supposed to stop at, it only takes half damage if hit. If there is a wall or other piece of terrain in the way, the francisca ricochets, and moves 5 feet (1d3 to determine where) and deals half damage to any creature that occupies the square it ricochets into.
A francisca can not bounce on exceptionally soft terrain, such as in a swamp, or on thick, untrodden snow. It can not ricochet off of wood, and instead sticks.

The black square is the one occupied by the original target, the red
squares are the ones that the francisca tries to move into (note there
are 12 of them), and the yellow squares are, of course, the ones that
the francisca moves through to get to one of those squares.
