// It says the chance for each item category is the matrix amount * the level of the NPC. Actual behavior in the
// released game is (matrix amount * PC level) for the first 4 item categories (temperate plants, warm plants,
// miscellaneous monster, warm monster), and just matrix amount for the categories after that.
// The second part of the DF Chronicles explanation (roll repeatedly for items from a category, each time at halved
// chance), matches the game.
// In classic, since a 0-99 roll is compared to whether it is less or greater than item chance,
// even a 0% chance category has a 1/100 chance to appear, and the chance values are effectively
// 1 higher than what the loot tables show.
