Arrow Cannon

You create a Arrow Cannon trap at the point you touch, the trap can only be created on walls.

The spell causes the wall surface to become flat, so creatures with a Passive Perception of 15 or higher can spot the trap from a range of 15 feet.

The trap measures 5 feet in width and 3 feet in height, if someone stands in front of the trap for a full turn, it triggers and deals 25d12 + {the longbow bonus multiplied by 10} piercing damage to all creatures in front the trap within a range of 30 ft.

If used by a ranger - hunter, the range increass to 50 ft, the damage grows to 25d20 + {the longbow bonus multiplied by 10} piercing damage, and you will need a Passive Perception of 17 or higher to spot the trap from a range of 10 feet.
