The Bag of Hazard is a semi-magical item that fires 100 ball bearings and 5 caltrops if the holder has them on their person. If the user does not have enough ball bearings and caltrops   the Bag of Hazard acts like a normal pouch.

If the user pulls the string, the ball bearings and caltrops shoot out and spread, covering a 10ft square.

each ball bearing deals 1d2 

targets of large size take 10d2 damage and ball bearing are destroyed and caltrops are deployed in a 5ft square in front  of the bag 

targets of medium size take 5d2 damage and half of the ball bearing are destroyed and caltrops and 50 ball bearing are deploy in a 10ft around the target

for targets of small roll a 1d3 to decide if (1) a ball bearing (1d4) hits or (2) caltrop hits (1d10) or (3) it misses. all results hot or miss will leave a 10ft square of caltrops and ball bearing

for targets of small roll a 1d4 to decide if (1) a ball bearing (1d4) hits or (2) caltrop hits (1d10) or (3-4) it misses. all results hot or miss will leave a 10ft square of caltrops and ball bearing
