Following the update from a day ago https://piratemc.com/topic/changelog-cannon-projectiles-ender-pearl-teleport-diamond-iron-golems/

We are adding more Cannon projectiles, some may turn out to be overpowered, but its best to just add as many ideas as we can think of, test them and tweak as needed, so make sure to give feedback from use (Not theoretical worries, issues that have happened).

• Added Blinding Shot Projectile, Fire an Ink sack from a 3 Long coal cannon, to blind your enemies.
• Added Rotting Corpse Shot Projectile, Fire a Zombie head from a 3 Long coal cannon to poison your enemies.
• Added Weakness Shot Projectile, Fire a skeleton head from a 3 long coal cannon to weaken your enemies.
• Added Smoke bomb Projectile, Fire Charcoal from a 3 Long coal cannon to leave a large smoke bomb to obscure vision!

Report any issues (Not theoretical ones) here.
