 * Making zombies float up into the air, instantly killing them. This has a 20% chance of happening. This does not apply to gargantuars and bosses, but imps can be lifted up from the gargantuars.
 * Making zombies slow down by making the gravity heavier. This has a 50% chance of happening and will slow down any zombie, including bosses. This effect lasts for 15 seconds.

Strategy
