I just noticed that while the tazer needs 100 charges to fire. If it has less than 100, it will still fire, give the “your tazer has X charges but needs 100” and will not use any charges. I just killed a school full of zombies by funneling them into a doorway and tazing them to death one at a time. as long as the tazer has a charge in it, it will continue to fire. I found this in experimental build 0.A 1515.
[edit]
either im very lucky, or boomers and spitters killed in this manner dont have their usual death effect. the two boomers didnt mess my vision up.
also, because of the stunning effect of the tazer, its possible to juggle three zombies at once without taking a single hit.
further tests (using debug to spawn monsters) have shown me that this method can be used to kill ANYTHING. ive spawned a flying polyp, a thing, a couple dark worms, and an amigara horror. as long as you hit them with the tazer before they can hit you first, their isnt a whole lot they can do to stop you from stomping them with your tiny tazer/tesla coil.
