The strangler is a rare poison, which makes the person unable to breathe. The poison is made from plants that are only found on islands in the Jade Sea. The leaves of the plant are picked and aged, then soaked in a wash of limes, sugar water and rare spices from the Summer Islands. The leaves are then discarded, but the liquid is kept and thickened with ash and allowed to crystallize. It turns a deep purple color.
Sad thing is in actual mythology this is very accurate. But loki does always fix the problem and usually the other gods got something good out of it in the end like magical weapons and tools, so really the other gods should stop bitching cuz when loki cleans up his messes they get free shit out of it.
