Rework paralysis to avoid insta-death

Paralysis would mean instant death (even when hit by a lowly
floating eye), but this is not really an interesting mechanic.
It has been reworked to not be cumulative, such that it isn't
a death sentence, but is still very dangerous if the paralyzer
is faster than the player.
