This technique enables the user to better manage his inner power by reducing the size of his body, thus sacrificing physical power. The user's size category decreases by 1, minimum Tiny; if the user's size category already is Tiny, he cannot use the technique.

The user suffers a -4 size penalty to his Strength score and Strength checks, but gains a +2 size bonus to Dexterity checks. In addition, the damage dealt by his unarmed attacks is reduced by 1. His clothing and equipment do not adjust to match his new size category. The user's height and weight are one-half and one-third of their normal value respectively while under the effects of this technique.

The user gains a +1 bonus to Chakra Control and Concentration checks while under the effects of this technique.

When struck under the effects of this technique, the user must succeed a Concentration check (DC 10+damage done) to avoid losing control over the technique and ending its effects immediately.
