Description: This module uses snowballs as smoke bombs. When throw they leave a trail of smoke and will disperse a cloud of smoke that freezes mobs and gives negative potion effects to players.

Video Example: https://www.youtube.com/watch?v=ngwBTMkDVAo

What it does: A thrown snowball leaves a trail of smoke until it hits something. It then makes a cloud of smoke at that location with a radius of 5 blocks. Any mobs inside the cloud are given slowness 10 which completely freezes them. Any player inside the cloud is given slowness 2 and blindness for two seconds. After a player leaves the cloud, the effects will begin to wear off. Mobs cannot leave the cloud as they are rendered frozen. The cloud disapates after 400 game ticks. The module supports multiple smoke bombs at a time from different players. 

Other Modules needed: Custom Crafting will be needed to craft the named snowball with a recipe. A few commands will need to be modified to Spark's liking so it works with CustomCrafting. I have made some recipes for smoke bombs but these are just ideas. The actual recipe is up to Sparks and others. A command listed at the end of the One Click will need to be changed so that when you craft the extended version of the smoke bomb it will summon a cloud that will be killed after X amount of ticks rather than the standard 400. Simply replace the 400 in this cmd: kill @e[score_SmokeMarker_min=400]  to whatever length you deem balanced. You can use the FIND tool to search exactly where this command is listed in the One Click.

Use this command to summon your smoke bombs or integrate into CustomCrafting:

summon Item ~ ~1 ~ {Item:{id:minecraft:snowball,Count:1b,tag:{display:{Name:"Smoke Bomb",Lore:["Place in your last slot to use."]}}}}

HUZZAH! This module has been updated to only work with snowballs that have a custom name of Smoke Bomb and custom lore of "Place in your last slot to use.". This allows CustomCrafting to give you this special item and you can no longer use anvils to make working smoke bombs! Additonally, you must have the smoke bomb in your 8th slot (Last Hotbar Slot) for it to work. This fixes the bug where you could have just one real smoke bomb and use regular snowballs and they would still work. Finally, per request, I have nerfed the slowness given to mobs so that they have a slight chance of walking out of the cloud. Plus skeletons are no longer able to shoot arrows while in the cloud and creepers don't explode unless you get too close! Woohoo PS:I reduced the particle count for the cloud to 250 instead of 1000.
