Anti-shifter technology

all anti-shifter devices are powered by electricity. By using pain and electrical pulses in the right frequents the shifters are forced down into their birth form.

Pain
With the help of pain you can force a shifter down to their birth form.

Electrical pulses
With the help of electrical pulses in the right frequencies you can block a shifter's elemental power.

Choker
The choker is a necklace the shifters use as hand cuffs. It's an adjustable iron ring you place around the shifters neck. The necklace blocks out all elemental powers with constant electrical pulses. If the shifter tries to shift or to summon their element anyway the choker will pierce their skin with hundred small needles while giving the shifter a huge electrical shock which will give the shifter a black out.

Silver gun
The silver guns are guns which fire bullets who forces shifters down to birth form. They got the name from the tale of how silver bullets are the only thing that works on werewolves. Each bullet has a small battery inside which discharge on impact. The hit shifter will get an electric shock and be forced down to birth form. The effect will last for 30 seconds and during this time the shifter won't be able to use any of their abilities.

The silver gun is standard equipment for electrical agents, and they are taught to imideiatly fire a second bullet if the first fail to take effect.

The first silvergun was invented by Stanly, one of electricals inhouse inventors. He still keeps a bunch of early prototype guns in his workshop.

Repressor
The repressor is a sword like weapon mostly used by the chemical faction. the sword has two parallel metal blades. The blades has no sharp edge but it's made for impaling rather than cutting. The repressor can be folded down into a small metal square to store in a bag or trick humans it's not a weapon.

Surpressor
Supressors are gigantic repressors which can be wielded by a snifter in their titan form. There are only a few of these weapons as they are hard to make, hard to transport and should only be used in emergency.

Holding cells
The holding cells are made in metal which is conducted with the same electrical pulses as the choker has to block any elemental power.

Makeshift anti-shifter devices
Anyone who knows the electrical pulse frequency needed to block elemental powers can technically build their own anti-shifter tech out of a conductor and a battery.
