Absorbent Leech Seed

Rei uses wood release o create special seeds which she throws at a target. Once the necessary hand signs are created, roots shoot out of them and constrict the target - unless dodged. These chakra enhanced can't be cut with normal weapons and have only been shown to be cut with wind, or lightning, enhanced weapons or highly manipulated jutsu. The roots uses Rei's special chakra to keep them strong while simultaneously absorbs the enemy's chakra and life source. Rei can completely control the amount that the roots absorb, and can even top them at will.
