A new plaything!
Henzell says...
  1. Powerful enchantments have cumulative side effects on the body, represented by a magic contamination stat. When you get enough contam, you start glowing, and you can get mutations. But it decays - unless you are hasted or invisible. The mutations are 1/5 random, otherwise bad with a 50% chance of overriding mutation resistance.
  2. The following effects cause magical contamination: haste, invisibility, extending haste, controlled blinking, mutagenic artifacts, Disjunction, Irradiate, some spell miscast effects (Charms, Hexes, Translocations and Transmutations), cancelling effects using stasis, (some) distortion unwields.
  3. The contam timer triggers every 200-600 auts. If you have 5000+ (yellow) contam, there is a contam/12000 chance of getting a mutation (80% bad 20% random). If this happens with 10000+ (half way to light red) contam, there is also a 50% chance of releasing a magical explosion (random element, 3d(contam/2000) damage, radius rand_round(contam/15000) (min 1 max 9))
