Well, since 6 can hit you at one time, you should count the 30x6 damage (180) plus the increased damage from poison. While this cant kill a lot of HM monsters on the first shot, within three seconds they can walk onto the plate again if you have them in a pit they cant jump out of and its game over. (Exceptions being mimic, and possibly unicorn.)
