Need ideas for my crate item

[SnipedYall]

Aaron Burr's Dueling Pistol
Item - Bow
Sharp 5
Punch 1
Unbreaking 3

Special Ability - Fire's a "Lead Bullet" which is like a taser where it would fire a straight line where the user was looking but go 10-20 blocks. Upon impact the victim's lower ribs would be cracked and they would recieve Slowness II and then the lead bullet itself would give the victim Poison 1 for 30 seconds. Aswell as Wither II for 3 seconds.

I actually really like this idea. I'd have to ask Silas what the cooldown would be like though.
