Paralysis

Certain undead monsters such as mummies and vampires have the ability to slow you down by paralysing you. There are only two ways to get rid of paralisis, and that is to either use a healing spell, or wait a while for it to clear off. Paralisasis is deadly for paladins, because if you're are trying to run a mummy and you are suddenly paralysed, you'll find that if you don't heal fast then you're toast!
