Sylux's Affinty weapon in Metroid prime hunters. The shock coil fires a circuit of energy that locks somewhat on the enemy. If sylux is using the weapon it sucks out the health of his oppenent and adds it to his own. It is critizied "cheap" although the noobs that do critisize dont get that they have a alternate form.
"OMFG THE SHOCK COIL IS SO CHEAP."
"Stfu n00b, and use your alt."
