Hunger-causing monsters

[Mangojuice]

So for the next non-patch version of Z+Angband, I've decided to implement a new type of monster attack: attacks that cause hunger. Basically, it would drain your level of nourishment by a number of turns based on the monster's level.

So anyway, I think it's a neat idea, but could be tricky to implement in a way that isn't super super dangerous: after all, if a monster can make you hit starvation levels, it's like a paralysis attack that no resistance can help against.

I'd like to hear input on what kinds of monsters should have this ability. So far, here's what I'm thinking.

1. I'd like to make this a standard attack of all Wights, perhaps replacing their Drain Experience attacks, or augmenting it. (I've felt for a while that Wights were much less dangerous than they should be, maybe this would help.)
2. A hunger-causing jelly
3. A hunger-causing, multiplying worm mass
4. A hunger-causing snake
5. A hunger-causing mimic (perhaps the Lurker or Chest mimic)

Any other ideas? Comments?
