The target’s body begins to diminish in height, weight, and Body, as this Curse causes him to shrink more and more each day. Each time the Target fails a Contesting Roll against the Curse, it shrinks by one size category, reducing its Body score by 4 points and its Body by 2 points (minimum 1 for each score) and reducing its AC by 1. These reductions cannot be ameliorated except by returning the creature to its proper size by removing the Curse. These reductions also stack if a creature shrinks more than one size category. If the Target is already Tiny in size and fails another Contesting Roll against this Curse, it is shrunk to a subatomic size and liable to implode. This affects the Target as disintegrate (9th-level spell). Even if the Target survives, he is effectively incorporeal, invisible, and paralyzed while at subatomic size. He must Contesting Roll again once per day against a potential implosion.

Because the Target is unused to its new size and how best to move within it, the Target has DIS on all d20 rolls while shrunk. The target’s gear shrinks with it, though items the Target drops return to their normal size d100 minutes after being dropped. The damage the Target deals with weapons is halved each time it shrinks a size category. In addition, if the Target shrinks more than two size categories the range and area of effect of any Spells or magical abilities it uses is also reduced by 50%. The effects of deadly diminution persist even if the Target uses a polymorph effect to assume a different form.
