There are no instant kill potions in minecraft at the moment, just potion of harming, which can do 3 or 6 hearts of damage.
The command is: /effect [player name] 16 [time duration] [level of potion]
Netherwarts is a key component in potion brewing. I suggest going to the minecraft wiki for more detail on potion brewing.

you don't there is none
To make a splash potion, take a regular potion and put it in the bottom slots of a brewing stand. Then, put a piece of gunpowder on the top slot of the brewing stand and it will convert the potion to a splash potion.
To apply multiple effects to a single potion using a command block in Minecraft, you can use the /effect command multiple times in a single command block by separating the different effects with a semicolon. For example, you can use a command like /effect give @p minecraft:speed 30 1; /effect give @p minecraft:strength 30 1. Alternatively, you can create a custom potion with combined effects by using the /give command to specify multiple effects in a single potion item, but this requires knowledge of potion data values.
